i had sex 3 times around 2-3 weeks ago with my boyfriend and we used a condom, after that i had bad stomach pains/cramps and thought i was pregnant - i ended up getting my period last week but it was one day late. I now have these bad stomach pains again.... ive had them for about 5 days, ive also been stressed alot lately.

could there been a chance im pregnant or is it just stress?
