So long story short, I ended my period around Dec. 23 and 'had sex' the 28th. My period isn't due for a while longer (obviously)

I am still technically a virgin, but I had given him a bj (I don't think he ever came, I assume everything I tasted was just pre-cum b/c he was still hard.) and then we messed around some more and he just put the head in me.

At the time I hadn't even thought much of it, since a) he didn't cum in me (he wouldn't have) and b) he wasn't all of the way inside of me. But then it hit me- I've heard you can get pregnant from pre-cum and he was inside me, even though not far.

 It's been a week as of today.

I've been having slight cramps (which I find weird b/c I hardly ever get cramps after my period), they aren't like my usual cramps though. They feel like a mix between cramps, and sore muscles (like you have 1-3 days after working out) not bad, just slight cramps, kind of like a dull burning cramp if that makes sense, it's hard to explain a feeling. And today my breast seem swollen and they are tender. At first I was just like "cool beans, they're growing a bit" but then I was looking around online (because now that the possibility popped into my head, I can't shake it) and saw that both cramping and tender breast were symptoms... Now I am just frustrated because I could just be paranoid (I hope that is it) and by being so, I think I am having symptoms when I am not. I don't see how they would be starting when it was only a week ago. I just wanted to get some other people's input on it.

There was also a tiny bit (and I do mean a TINY bit) of spotting 2-3 days after that night (I just assumed it was because I hadn't done anything before, still think that's it)

I guess I am just mostly looking for someone to tell me I am being a stupid paranoid girl and that there is no way I am pregnant.

Any and all advice would be great! And trust me, from now on, even if I am not going any farther than I did, they will be wearing a condom.
