Patient's question:
Was the pregnancy before or after the menstrual period? My last menstrual period started on June 14th in the afternoon and lasted for six days. On the seventh day, it stopped. I had sex with my ex-boyfriend on June 10th, and from June 12th to after my period ended, I was with my husband. My last menstrual period was on June 14th. It wasn't until August 9th that an ultrasound showed a gestational sac. On September 19th, an NT scan indicated the fetus was 12 weeks and 5 days. On December 6th, a 4D ultrasound showed the fetus was 22 weeks and 2 days. Whose child is it? What is the evidence? Please help me clarify this, give me a definite explanation. If it cannot be confirmed, please do not explain. Thank you.Doctor's answer:
According to the situation you mentioned, confirming that your period arrived on the 14th, then it means you got pregnant after your period. Under normal circumstances, pregnancy would never occur before your period. After the period ends, the hormone levels in your body rise, and the ovaries begin to develop follicles. It takes about ten days for these follicles to mature before you ovulate, and only then can you conceive. Therefore, it was sexual intercourse after your period that led to the pregnancy, with no relation to sexual activity before your period. Moreover, according to your first ultrasound report, it was also your husband's.
