How accurate is my ‘due date’?

The first ultrasound in which one can see the pregnancy is something all parents look forward to very emotionally. This is more so for those, having gone through treatments for assisted reproduction. For such patients, after having a positive pregnancy test done, their anxiety does not actually go away but also gets stronger until the pregnancy is observed as developing normally. It is essential to know what happens during such exploration and also what to expect. It usually needs to be done between week 5 and 7 of pregnancy, and therefore between 3 and 5 weeks after the embryo transfer. The scanning is done exactly one month after the embryo transfer to observe whether the pregnancy is progressing or not. The ultrasound must also be done vaginally. This does show the images more clearly, and it is also more precise in showing that everything is evolving rather correctly.

If you have been pregnant, or if it has been more than one year since your last embryo transfer, a repeat uterine measurement should be performed before FET.

If you have never had an evaluation of the uterine cavity or if it has been longer than a year or if you have risk factors for uterine structural abnormalities, we will recommend a uterine cavity evaluation prior to FET, either with a saline infusion sonohystogram, office hysteroscopy or a hysterosalpingogram.
