Gestational sac implantation time

When most people are preparing for pregnancy, they will try to have sex with their male partners during their ovulation period, because the probability of pregnancy during this period is very high. However, pregnancy cannot be detected immediately after having sex, because it takes a certain amount of time for the gestational sac to implant, and the development of the gestational sac is relatively slow. So how long does the gestational sac usually last?

Many women will have sex with their husbands when they are newly married, and of course they will sleep in the same bed, but after sleeping in the same bed, they will consider another question: how to use the size of the gestational sac to calculate the time of implantation. Also, will the late implantation of the fertilized egg affect the size of the gestational sac? These are the questions that pregnant mothers think about when they are pregnant. Let me answer them for you one by one.

Calculate implantation time based on gestational sac size

Some doctors have indicated that the date can be roughly calculated based on the size of the gestational sac, but it is not very accurate because it is related to the time of implantation and fertilization. Therefore, it is not certain to use the size of the gestational sac to calculate the implantation time.

The doctor said that if you want to calculate the gestational age based on the size of the gestational sac, you should add the three diameters of the gestational sac, divide it by three, and then add 30 to get the number of days of pregnancy.

Will late implantation of the fertilized egg affect the size of the gestational sac?

There is no necessary relationship between the size of the gestational sac and the early or late implantation.

Due to the pregnant mother's emotional tension and other reasons, the menstruation is delayed, the ovulation period is delayed, and the conception time is late, resulting in the gestational sac being smaller than the actual number of days of amenorrhea. For example, the menstruation has not stopped for 50 days, but the examination finds that the gestational sac is only about the size of a 40-day gestational sac.

It is normal for the gestational sac to be small. As long as a week of dynamic examination shows that hormones and some numerical values ​​are gradually increasing, the gestational sac is continuing to grow, and the fetal bud and fetal heartbeat gradually appear, it means that the small gestational sac is due to physiological reasons such as delayed ovulation and late conception, but the pregnancy can continue.

Due to poor development of sperm and eggs, infection of mycoplasma, chlamydia, rubella virus in pregnant women, or exposure to toxic and harmful substances during pregnancy, the gestational sac may be poorly developed and smaller than normal.

For pregnant mothers who experience the above situation, the gestational sac will continue to grow as time goes by during pregnancy, but no fetal bud or fetal heartbeat can be seen. In this case, the gestational sac is unhealthy and will eventually lead to miscarriage.

The above are some answers and suggestions from the editor on how to use the size of the gestational sac to calculate the implantation time and whether the late implantation of the fertilized egg will affect the size of the gestational sac. Although there is a certain relationship between the size of the gestational sac and the time of implantation, an accurate estimate should be made under the examination of a doctor. Pregnant mothers should prepare for the advanced pregnancy as early as possible, take folic acid supplements regularly, and do prenatal checkups, so that the fetus can develop healthily.
