Patient's question:
My period sometimes comes and sometimes doesn't, anyway it's not on time. Yesterday I had a thorough check and found out I'm pregnant, but I don't know how far along I am. How long does it take for a gestational sac of 4 cm to develop? What kind of help do you need: How long does it take for a gestational sac of 4 cm to develop?Doctor's answer:
After getting pregnant, one cannot directly see how big the baby is inside the stomach, especially in the early stages when the belly doesn't shrink noticeably. It can only be guessed through careful examination. For a normal intrauterine early pregnancy, a careful ultrasound examination can usually detect the intrauterine embryo and the fetal heartbeat around the 50th day after the menstrual period. Due to the growth and development of the embryo, the 30-40-day stage forms the gestational sac, while the 40-50-day stage forms the embryo.
