Hi there,
It may be difficult to determine the exact answer of your problem without a complete medical evaluation. It all depends on the dates you had sex .It is quite possible that you conceived on February 14th since expected date of delivery is calculated 9 months and 7 days after the last menstrual period. Visit a gynecologist for more queries and assistance. Keep me posted.
Best luck and regards!
Mmmm well all the sites I've visited and research all say that my last period was suppose to be on february 15 && that my conception date was march 1st does that change anything?. The other guy I slept with I don't remember tthe dates but I do know it was after february 14.
