Me and my boyfruend had protected sex on the Friday that just past. Now I'm feeling very nauseas and bloated and some stomach pains. I just got my period but its very light. Lighter then usual. Why would it? And is there any chance I could be pregnant. I hope not, I'm only 17 :(

Age does not limit if u are more than 14 the chance is present but as u say that u have little menses than the chance of pregnancy has been minimized

Anytime you have a penis inserted into a vagina you risk pregnancy. By using contraception you lowered the chances, but it's still possible.

With that said, you only had sex 3 days ago. It would be too early for any symptoms to be occurring. Since you are on your period this month, you will have to wait until next month to see if your period comes.
