Sex a Week Before Period, But Period Never Came

Emma (age 16) writes:

I had unprotected sex a week before I was supposed to get my period. My boyfriend did not cum in me. I took a pregnancy test on the day that I first missed my period. I waited for about another week, and took another pregnancy test. Both results came out negative. I am on no birth control and haven’t taken any emergency contraceptives. My period is still a week late, and I never missed my period before. I have no symptoms of early pregnancy. Is there a chance that I might be pregnant?

Dear Emma,

Do you have sex frequently with your boyfriend or was this a first (or at least a rare occasion)? If you really did get pregnant from that incident, and you took a home pregnancy test just a week later, that would most likely be too early to detect hCG (the pregnancy hormone) in your urine. If you and he are totally certain that he did not ejaculate inside you, there would be the slight risk of some sperm being inside you from what some call pre-cum, but the chances of getting pregnant from that are very slim.

If this was the first time you had sex in a while, it’s not uncommon to have your period get messed up (got to love our bodies and nerves!). Have you recently changed how you exercise or your diet? Both of those love to mess with our cycles too.

To err on the safe side, I would recommend taking another home pregnancy test (HPT) in 2 weeks from now and then another one 2 weeks later. Most likely you are not pregnant, since there shouldn’t be much if any sperm that entered your body.

Keep us posted please!

    Had sex on the 28th. I am irregular but I was supposed to start around the 8th (just like last month) and haven’t. I am bloated, fatigued, and have had an upset stomach since like 3 or 4 days after the sex. Am i just stressing too much or could i be pregnant?
