I'm eighteen years old. My period ended four days ago and it was a normal heavy period. My boyfriend and I have been having unprotected sex for the past week. I feel constipated with tiny sharp pains in my stomach. I feel slightly nauseus every so often. Could I be pregnant? I'm also peeing little more than normal and I seem to be extra tired lately.

You may be, but these would not be signs for that, just days after sex.

While it does not happen frequently, it is possible to become pregnant, while on period.

So not, you just wait till next month, and see if that period comes.

I would consult with your doctor about gastrointestinal issues. You've had a period, chances are you're not. If you're not wanting to have kids I would suggest also consulting with your doctor about proper birth control, or stop having sex.

Are you hoping for a boy or girl? Perhaps twins or triplets? That's the eventual result of unprotected sex.

As far as if you are pregnant yet or not...its far too soon. You have to be at least 2 weeks late for a period before you can get a reliable test result.

I know what the result is of having unprotected sex I'm not stupid. I was just wondering if those symptoms match up since it's too early to test.

The symptoms you are having are similar to several illnesses, not just pregnancy. Pregnancy cannot be diagnosed by symptoms alone.

You are now playing the waiting game. You need to wait to see if your next period comes as expected. If not, wait two weeks and then test using first morning urine.
