Patient's question:
My last menstrual period started on June 14th in the afternoon and lasted for six days. It stopped on the seventh day. I was with my ex-boyfriend on June 10th, and with my husband on June 12th and 13th, as well as after my period ended. My last menstrual period was on June 14th. It wasn’t until August 9th that I was confirmed to be pregnant. On September 19th, an NT scan showed the fetus was 12 weeks and 5 days. On December 6th, a 4D ultrasound showed the fetus was 22 weeks and 2 days. I want to know who the child belongs to? Why does each check-up show the fetus being two or three weeks younger than the last menstrual period?Doctor's answer:
Generally, if you are menstruating, it proves that no matter how many times you had sex before your period, you will never get pregnant. This child must be your husband's. As for the fact that your pregnancy duration is shorter than your missed period duration, it is very likely due to late menopause. Apart from the occasional case where fetal growth and development may again be shorter than the missed period duration. The above suggestions are for the question "Why does each examination show the fetus is two or three weeks smaller than the last menstrual period?" I hope it helps you. Wish you health!
