Question
How do I calculate the date of pregnancy? If my menstrual cycle is every 30 days, then my pregnancy date should be May 22nd. I took the birth control pill on the 19th, but the medication seems to have no effect because I am still growing and developing normally. I had an ultrasound on July 13th, and the ultrasound showed that the embryo was about 40 days old, which matches my last menstrual period date. Are you pregnant before or after taking the birth control pill?
Answer
Based on your description, you should be calculating the date of pregnancy from the last menstrual period. The ultrasound you had on July 13th indicated that the embryo was approximately 40 days old at that time, which aligns with your last menstrual period date. It is recommended to avoid spicy foods during pregnancy, quit smoking and drinking, and take folic acid supplements in the months before and after conception. Additionally, regular prenatal check-ups are very important, and specific situations should be determined based on your personal circumstances. Please provide more information about when you took the emergency birth control pill.
