So I need Advice (TMI)

So me and my crush had sex, like multiple sessions. Like the idiot I was we didn't use protection, since he had none. He didn't finish in me and pulled out, he accidentally let some drip on top of my vagina tho, like where my lips start on top if that makes sense, so I'm 99% sure it didn't go past or anywhere in my inner thigh area but lately I have had some acid reflux, i feel like I'm going to throw up, and my stomach has been cramping a bit. Is that normal?? Is it a sign of pregnancy?? I am again 99% sure he didn't let any drip down there all the way or completely so I should be fine I hope. If it isn't a sign of pregnancy then does anyone know what it could be? I just really want to know

Update Real Quick: Since I was told that stressing over it can cause false symptoms, i also learned that anxiety can also cause acid reflux and I have a high amount of that so that could be the possibility as well. If anyone knows anymore on that fact I'd also like some advice on that please
