You do not need to stay in bed after an embryo transfer. You can return to work, go for a walk, or do your daily chores at home the day after the transfer. During this period, it is common to experience mild pulling in the groin or see a few drops of brown spotting on your underwear. These do not mean anything on their own. The result is shown by the beta hCG blood test on the day your physician has given you.
This two-week period is called the "waiting period" among patients, and it is usually the most difficult part of the treatment. There is nothing to do but wait. These are the questions we hear most often in the clinic during this period. We have answered these questions one by one below.
Do you need to lie down after the transfer?
No. For many years, it was recommended to lie down for days after the transfer. Today, the studies we have show that bed rest does not increase the chance of pregnancy. Some analyses have even reported that results are slightly worse in those who remain inactive for a long time.
When the embryo is placed in the uterine cavity, it does not "fall out" when you stand up. The uterine cavity is not like an open room. It is an area where the front and back walls touch each other, with almost no space between them. The embryo stays between these two surfaces. Going to the toilet, coughing, sneezing, or climbing stairs does not change the position of the embryo.
Resting for about 15-20 minutes after the transfer is sufficient. It may feel good to spend the day quietly after returning home, but this is not a medical necessity.
The waiting period day by day
The table below is for a 5th-day (blastocyst) transfer. In a 3rd-day transfer, embryo implantation occurs about two days later. Therefore, the test day also shifts about two days later.
| After transfer | What happens to the embryo? | On your side |
|---|---|---|
| Days 1-2 | The blastocyst begins to hatch from its outer shell (zona pellucida). | There may be mild cramping or pink-brown spotting caused by the catheter. |
| Days 2-5 | The embryo attaches to the uterine lining and implants into it. | Most people feel nothing. The soreness felt is usually progesterone-related. |
| Days 5-9 | Cells that will form the placenta begin to produce hCG hormone and its level in the blood rises. | The days when the urge to take a home test is most intense. Early testing can be misleading. |
| Days 9-11 | hCG reaches a level that can be reliably measured in the blood. | The beta hCG blood test is usually performed in this range. The day may vary depending on the center. |
| Days 12-14 | In a 3rd-day transfer, hCG reaches a measurable level these days. | For those who had a 3rd-day transfer, the blood test is usually performed in this range. |
Groin pain, spotting, breast tenderness: Are these signs of implantation?
This is the most discussed topic in forums. Most of the things felt in the two weeks after the transfer are caused by the medications you use. Progesterone causes breast fullness, bloating, fatigue, pulling in the groin, and mood swings. These are almost identical to the complaints seen when pregnancy begins. In other words, there is no reason to think "I have symptoms, it definitely worked" or "I don't feel anything, it didn't work."
The situation is similar for spotting. Since the cervix is touched during the transfer, there may be brown discharge for the first day or two. In patients using vaginal progesterone, the medication itself can also color the discharge. A few drops of "implantation bleeding" may be seen on the days the embryo implants, but this does not happen to everyone, and not having it does not mean anything.
If there is bleeding that overflows the pad, is as heavy as menstrual bleeding, or contains clots, notify your physician without waiting. Such bleeding does not always mean the result is negative. But it needs to be evaluated.
How should you use progesterone support?
In IVF treatment, the ovaries' own progesterone production is often insufficient. In frozen transfer cycles prepared with hormone medications, all progesterone is given from the outside. Therefore, progesterone support is the most important part of this period. It can be in the form of a suppository, gel, injection, or tablet.
- Use the medication at the same time every day. If you realize you forgot, take it immediately and inform your physician.
- Do not stop the medication on your own decision, even if there is spotting. Bleeding is not a reason to stop progesterone.
- The support continues for a while even when the beta hCG comes out positive. Your physician will tell you when to stop.
- There may be discharge and itching after vaginal suppositories. This is usually the residue of the medication. Report it if there is a bad odor or burning.
Why can a home pregnancy test be misleading?
In fresh transfers, the "trigger shot" given before egg collection may contain hCG. The hCG in the injection is cleared from the body in 10-14 days. In frozen transfers, this injection is often not given. A urine test performed a few days after the transfer may therefore come out positive even if there is no pregnancy. Conversely, even if the embryo has implanted, the hCG level may not have risen enough to pass into the urine in an early test. An early negative test will also upset you unnecessarily.
Many patients check whether the line is darkening by testing every day. We recommend that you do not do this. The color of the line varies depending on the concentration of the urine, the brand of the test, and the time. Comparing day by day does not give an accurate result. The blood test gives the result.
How to read the beta hCG result?
Most laboratories consider below 5 mIU/mL as negative. Between 5 and 25 is considered borderline and is usually rechecked after 48 hours. Higher values indicate that pregnancy has begun. However, it is difficult to tell how the pregnancy will progress from a single number. The tables circulating on the internet asking "what should beta be 10 days after transfer" are compiled from different patient groups of different centers and do not reflect your situation exactly.
The rate of increase is more important than a single value
When the first result is positive, the test is usually repeated after 48 hours. In most healthy early pregnancies, hCG increases by at least 35 percent in 48 hours, and often doubles. If the increase is slow, the value remains the same, or it is decreasing, the situation is clarified by making a few more measurements. There are also pregnancies that start low and progress healthily. Therefore, do not lose hope immediately just because the first number came out low.
What happens next?
When beta hCG reaches a sufficient level, approximately 3 weeks after the transfer, the gestational sac is checked with a vaginal ultrasound. The baby's heartbeat can usually be seen 1-2 weeks after this. In an IVF pregnancy, the gestational age is calculated precisely according to the transfer date and the age of the embryo.
If the test is negative or the pregnancy does not progress, this does not mean that the next attempt will result in the same way. In the meeting you will have with your physician, the development of the embryos, how ready the uterine lining is for transfer, and the timing of the transfer are re-evaluated. If necessary, additional tests are planned for other factors that may affect implantation.
What is allowed and what should you avoid during this period?
What is allowed:
- You can return to desk jobs the day after the transfer.
- Walking, light housework, and driving are allowed.
- You can take a shower at a normal temperature.
- Eat as usual. There is no scientific data showing that there is a food that "increases implantation" or a special diet such as pineapple or walnuts.
Things we want you to avoid:
- Smoking and alcohol. Passive smoking is also included.
- Heavy lifting, running, jumping, and sports that strain the abdominal muscles.
- Sauna, Turkish bath, thermal springs, and hot tubs.
- Starting a new medication, herbal product, or supplement, including painkillers, without asking your physician. Paracetamol is usually preferred when a painkiller is needed.
There is no strong evidence that stress alone prevents embryo implantation. Even knowing this comforts some patients. The thought "I couldn't stay calm enough, so it didn't happen" creates both a wrong and unnecessary feeling of guilt.
Call without waiting for the test day in these situations
- Rapidly increasing swelling, tension, or severe pain in the abdomen
- Shortness of breath, significant decrease in urine amount, or gaining more than 1 kilo per day (may be a sign of ovarian hyperstimulation syndrome)
- Heavy bleeding that overflows the pad or contains clots
- Fever above 38 °C
- Unilateral swelling and pain in the leg
Where can you have the blood test done?
Clarify with your physician which medication to use at what time after the transfer and the day of the blood test. If you have any questions, you can call our IVF Center. If you have the beta hCG test done in our hospital's laboratory, you can see your result on the online result screen.
