it may just be me being paranoid

So, I'll try to tell you guys everything just so you could give me your best answers, this may be a stupid question, I have terrible anxiety so it's not because I'm uneducated,  I am educated, I try to learn as much as I can so people could stop calling me retarded. 
Okay, so let's start with losing my virginity, I lost it a week or so before my period, it was in the heat of the moment and I didn't use protection, the second time we did that too, it was a few days after losing my virginity. He didn't cum inside of me or on me or anything, we used condoms every time after and I'm going on birthcontrol because I know not being protected is a bad idea and I won't do that again, ever. 
Well I got my period and it was a day late (which is normal for me) and it was like a normal period for me, after my period I had sex with a condom, he pulled out and then he came, well I felt slightly bloated for a few days and I keep worrying about pregnancy, my period is due in a week or so and I'm getting those pre-period emotions and stuff but that could also be pregnancy signs and I'm soooo scared because I made a mistake and I won't do it again but I still might be pregnant, I have such bad anxiety I couldn't be able to go through pregnancy, I'm not emotionally stable and you may say "abortans" I don't think I'm mentally stable for that or giving a baby away at all, or going through pregnancy at all.. I don't know- it's weird I know.. but, I would like to know you're opinions. Thank you for responding, if you want to be rude or sassy, please don't waste your words on me.
