Should I be worried??

Okay so Im kind of in a pregnancy scare rn you've probably seen the posts and how scared I actually am that I might have made a mistake.. And you can say I'm stupid and not mature maybe I am but if u have seen the posts last Sunday me I have my bf oral and he came in my mouth which I swallowed a couple minutes after swallowing I kissed him and he stuck his finger in his mouth and kinda poked slash touch me down there. I'm suppose to get my period in about 4 days and I usually have these weird feelings before it comes but I haven't do yours somtimes come like surprisingly? and  I've been peeing more people say that could be a pms symptom too I'm just really worried and nervous your responses would be helpful thank you😔
