I can give an "estimate" but I really don't know because I never keep track.(Plus I have always been told that because of metabolic issues, and PCOS that it would be very hard for me to get pregnant).At around seven weeks of pregnancy, it’s reasonably common for women to have their first ultrasound.This can be for many reasons but the most common is to confirm pregnancy and to check that the embryo is viable and “everything’s ok”.Obstetric ultrasonography is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in its mother's uterus (womb).The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus.Ultrasound scans are considered to be the most cost-effective, accurate and safe methods for measurement of various fetal parts in pregnant women.
