The question
Dear TeenHealthFX,
So on October 27th was the first day of my last period it lasted until November 3rd we had tried for a baby on November 9th and I took a pregnancy test on December 7th and I was pregnant so I guess my question is, is it possible to conceive in one day? I just don’t understand how I could get pregnant off of having sex one time

The answer
Yes, it is possible to get pregnant after having sex one time. Anytime ejaculation occurs in or around the vaginal area, pregnancy can occur. Sperm can live inside the human body for several days and it is very difficult to track the exact time you ovulate. This is results in a larger window of pregnancy even if it was just one time. We hope this helps!
