Patient's question:
I had my last menstrual period on May 30th, but I took birth control pills on May 8th, which caused the period to come on the 30th. Is the last menstrual period based on May 30th? I had sex after that and didn't get pregnant until the 15th, and I didn't take any birth control pills. Then on the 18th, I had sex and took the birth control pill around 9 a.m. on the third day. The ultrasound result on July 13th showed I was about 5 to 6 weeks pregnant. The doctor told me that since the baby could develop normally, taking the birth control pill on the 19th would be useless—if it had any effect, the baby would be miscarried. Later, the doctor asked if I had sex after taking the pill on the 19th, and I said yes. Then the doctor said that the egg I took birth control pills for was released first, and then it was fertilized. What I want to know is whether I was already pregnant before the 18th or if I got pregnant after having sex after taking the pill on the 19th. I don’t need any other explanations—I just want to know if I was already pregnant before the 18th or if I got pregnant after having sex after taking the pill on the 19th.Doctor's answer:
Dear consultant, hello, it's impossible to be accurate unless you only had intercourse once between two menstrual periods and gave birth successfully, then you might be able to accurately know the day you conceived. It is usually calculated from the first day of the last menstrual period, and the entire pregnancy lasts 280 days. This is the entire introduction to "Did you get pregnant after taking medicine and having sex?" Finally, wish the patient a speedy recovery and a healthy life.
