Just Paranoid or...?

So, I started my new pack two days late (I’m on the pill) and I heard that taking the first few pills of a pack is critical because it puts you at risk of ovulating if you don’t.

Well, within one of those two days my boyfriend and I were messing around. We didn’t have intercourse but he rubbed the tip of his dick up against me, if you know what i’m talking about. (This happened a week ago)

He didn’t cum but I know there’s a slight possibility that you can get pregnant from pre-cum, and you can get pregnant even if there’s sperm outside of you that’s close enough to make it’s way in. I know the possibility of that is highly unlikely and the fact that it was pre-cum makes an even slimmer chance of a pregnancy happening.

I’m only 16 so i’ve been stressing over the possibility for days and just overthinking. I feel like i’m having symptoms but i know it’s way too early for any of that since it’s only been a week. I honestly think i’m just extremely paranoid and picking at every little thing that happens to me and making myself think it’s a symptom.

I think I just need some reassurance. Again, I’m sorry for the long post.
