Your Question:

I am having lower abdominal cramps on and off throughout the past 2 days. Me and my boyfriend had sex without a condom 2 days ago but he didn't in me and I have been on birth control for 4 years and I take them like there supposed to be taken. Last Friday I started my period but I had sex 5 days before my period and my boyfriends condom came off in me after he came. I was able to pull it out. Me and him are concerned I may be pregnant?

You will have to see if your period comes as expected. Pregnancy cannot be diagnosed by symptoms alone.

The signs can be nothing or several things. No way to tell from that.

Missing your period is the first good sign, if you miss a period, you wait 14 days and then do pregnancy test
