Help I’m scared

Like this is the first time this has happened to me, and like since my little hoe ass had sex within the two days after my period and before my fertility window, and now my nipples are sensitive (not hurting, like if I run my finger over them I can really feel it) and my stomach feels weird and I kinda feel nauseous but not really. (It’s not like to the point of metallic taste in my mouth, it’s like a pressure under my tongue)

It literally has all happened within the first week of me having sex, like my boyfriend and I did it once normally (with condoms, and he pulled out) and then I gave him a hand job in a hottub (I know I’m nasty and I’m sorry) he came in the water and then I was scared like two minutes afterwards because of that dumb myth so I got out.

Like I’ve been on birth control for 3 months, I have never missed a pill, and I take it every day at 10 pm on the dot. I also have anxiety so it would make sense that every time I think about getting pregnant I get that nauseous feeling and my stomach feeling weird. BUT WHY DOES MY NIPPLES HURT (FEEL REALLY SENSITIVE) 😂😓

Like I would not be stressing if they weren’t more sensitive than usual... like I’m on my fertility window... I just ovulated yesterday. I’m not good with this type of thing, could it have something to do with that?

(Ps I’m definitely taking a break from sex for a while if I’m not pregnant. Gawd I’m scared)
