In calculating pregnancy after IVF, it’s clear on which day fertilization occurs, unlike normal pregnancy. Since you will follow your natural menstrual cycle in IVF procedures, the date of embryo entry into your uterus coincides two weeks after the first day of your last menstrual period. You can calculate the probable date of birth by adding 266 days (38 weeks) to the day of the embryo entering your womb. If the B-HCG test is positive 12 days after the embryo is placed, that is, if pregnancy has occurred, the gestational week is considered to be four weeks.

When Does Pregnancy Occur in IVF?

IVF methods used for couples with infertility problems are extremely promising. There is no guarantee that pregnancy will occur in this method as natural pregnancy. In many IVF treatments, pregnancy may not happen in the first attempt. Pregnancy can occur after 3-4 shots on average. Before applying for IVF treatment, you should decide by considering that you will try it several times. After IVF treatment, there is a certain waiting period to determine whether the pregnancy has started. After embryo transfer or 15 days after fertilization, you can get a clue about the pregnancy status by doing a urine test or blood test. Although this process is a bit tiring, you need to wait about two weeks to determine whether pregnancy has occurred after IVF treatment.

Pregnancy Calculation in IVF Treatment

The methods of calculating the gestational week of expectant mothers who become pregnant with the in vitro fertilization method may vary. The drugs used in IVF treatment may cause the date of the last menstrual period to be misleading. Couples who are less likely to have a baby can have the opportunity to have a successful pregnancy with the IVF method. You can take egg collection, blastocyst or embryo transfer dates as a starting point to calculate pregnancy after IVF treatment, which is a complex treatment process.

  • In calculating pregnancy with IVF, the embryo transfer date coincides with the 2nd week of pregnancy. This is because fertilization of egg and sperm cells takes place in 2 weeks.
  • In the IVF method, since the day the embryo is placed in the uterus is clearly known, it can be said that the approximate date of birth will coincide with 266 days after this date.
  • Multiple pregnancies can occur if more than one embryo has entered the mother’s womb. Although multiple embryo transfer is considered riskier than the normal process, this method increases the possibility of pregnancy in some cases. In the case of multiple pregnancies, the pregnancy calculation isn’t different from the pregnancy calculation used in the IVF treatment method.

Does IVF Pregnancy Week Calculation Change in Multiple Pregnancy?

Multiple pregnancies are indeed more risky than normal pregnancies. If there are embryos that aren’t fully fertile, more than one embryo can be transplanted to increase the probability of pregnancy. Multiple pregnancies will occur when more than one embryo is placed in the uterus.

The methods of calculating the week of pregnancy IVF are the same for expectant mothers who have had multiple pregnancies. However, the duration of the pregnancy to result in childbirth is shorter here. Twin babies are born on average 21 days before the gestation period, which is 280 days. For expectant mothers with triplets, this period can be accepted as an average of 49 days earlier.
