How to calculate gestational weeks after IVF pregnancy
IVF is a method to help couples who cannot conceive naturally to conceive children through assisted reproductive technology. After IVF pregnancy, the calculation of pregnancy week is different from that of natural pregnancy. This article will elaborate on how to calculate pregnancy weeks after IVF pregnancy from the following aspects.
Calculation of pregnancy preparation period
For couples with IVF babies, the calculation of pregnancy preparation period is the basis of pregnancy weeks after pregnancy. Generally, the pregnancy preparation period starts from the first day of the menstrual cycle. Both husband and wife need to go to a formal assisted reproductive hospital for a comprehensive examination to ensure that their physical conditions are suitable for IVF operation. The doctor will determine the ovulation period according to the length of the woman's menstrual cycle and the basic temperature chart. "Ovulation period" refers to the time when eggs are released from the ovary during the menstrual cycle, which generally lasts for 24 hours. According to the ovulation period, the doctor determines the pregnancy date of the fertilized egg.
The pregnancy preparation period is generally 21-35 days, and the woman will have sexual intercourse 2-3 days before and after ovulation, or do IVF assisted reproductive technology at a specific time. The goal is to increase the chance of successful pregnancy. Generally speaking, the pregnancy preparation cycle needs to be adjusted and prepared before IVF surgery.
After the pregnancy preparation period, the first day of pregnancy means the beginning of pregnancy week.
Calculation of gestational weeks
After IVF pregnancy, the calculation of pregnancy weeks is different from that of natural pregnancy. The pregnancy weeks of IVF are calculated from the date when fresh embryos (embryos in the last specific stage before transfer) are transferred to the woman's uterus. The doctor will provide the IVF couple with an exact transplant date, and then calculate the weeks of pregnancy from that date.
The common calculation method is the number of weeks of pregnancy=the number of days since the date of transplantation ÷ 7. For example, if the embryo transfer date is January 1, 2022, and today is March 1, 2022, then the number of weeks of pregnancy=(March 1, 2022 - January 1, 2022) ÷ 7=8 weeks.
Relevant inspection and monitoring
After IVF pregnancy, doctors will carry out a series of relevant examinations and monitoring to ensure the healthy development of embryos and the stability of pregnancy. Routine examination items include regular ultrasonic examination, blood test, urine test, etc. The doctor will determine the time node of the examination according to the calculation of the gestational week. Through these examinations, doctors can understand the size of the embryo, heartbeat, organ development and other conditions, and timely find and deal with potential problems.
In addition, doctors will also pay close attention to the physical conditions of IVF mothers, including blood pressure, weight, blood sugar, etc., as well as possible complications during pregnancy, such as gestational diabetes, gestational hypertension, etc.
Summary
After IVF pregnancy, the calculation of pregnancy week is different from that of natural pregnancy. The calculation of pregnancy preparation period is the basis of pregnancy week calculation, and the pregnancy preparation time is determined according to the menstrual cycle and ovulation period. The number of weeks of pregnancy is calculated from the date of embryo transfer. Relevant inspection and monitoring are very important for embryo health and pregnancy stability.
After IVF pregnancy, the couple should visit a regular assisted reproductive hospital, cooperate with the doctor's inspection and monitoring, and follow the doctor's advice and guidance to ensure the smooth development of IVF and the health of the mother. At the same time, couples should maintain a good attitude, believe in the power of science and technology, stick to it, and work hard to realize their dreams.
