Paranoid After Losing My Virginity

My boyfriend and I of 2 years decided to have sex on Feb. 18, I can't remember when I stopped my period but I know it was a couple days before Valentines Day which is the 14th.

-He used a condom (Trojan ENZ Premium Latex and Lubricant)

-He did NOT ejaculate inside of me, he pulled out before he ejaculated. Yes, he still had the condom on.

-We kept checking during sex (I know, unromantic) if the condom was still okay, and it seemed to be. It didn't break or have holes in it.

Im supposed to get my period around the week of the 10th in March. Ever since I had sex for the first time, i've been so paranoid that I am pregnant or something.

The day after I lost my virginity, I felt odd. I was looser down there (which is normal), I had a very tiny cramp and a tiny bit of a lower back pain. Nothing major though. I've been having discharge, but it seems to be of normal color (clear-white-yellowish sometimes). I was fine with no symptoms for a while, and then since my period should be coming up in the next week. I'm experiencing pre-menstrual cramping it seems like, but at the same time I am paranoid about this.

I have talked to many friends and they told me I shouldn't be worried.

My boyfriend keeps telling me that the condom was not broken and nothing happened to it. I know nothing happened to it because I actually saw it, but I don't know why my mind keeps insisting something wrong happened. When nothing did....

I also called Planned Parenthood and they said that I used two forms of protection, condom+pulling out, so that increases my chances of safety.

I don't know why I have been paranoid
Every little pain or or discharge I see, I get worried.
