Jan. 25 I had sex with a friend but the condom broke. My period came 2 weeks later but it was a few days late. I had a pretty regular menstrual and it lasted the normal 6 days. But since then, I've been feeling "off". I have really bad heartburn and I rarely eat spicy or highly acidic foods, I've had slightly mild cramps right below my stomach, and I have trouble sleeping during the night because I tend to sleep very often during the day. I took a pregnant. Test but it showed up negative. Could I still be pregnant?

It's possible, but the odds are in your favor that you aren't. Wait until your next period would be due and test at that time if it doesn't show.
