Stupid question but my anxiety is relentless.

So according to this app which I hear can be inaccurate, I was ovulating may 1st with my highest risk of pregnancy days at apr 29th. I had sex that day but he finished in the condom. But, we grinded naked afterwards with his dick in the lips of my vagina going back and forth. But it wasn’t directly after sex we waited some time. Sometimes the opening of my vagina goes on his tip but I remember looking down and seeing I was mostly on the shaft. Precum is worrying me, but when he finished I was far away. I’m extremely paranoid about a lot of things and this is #1. I feel like my body is playing games with me. I’ve had sore boobs for days but they’re starting to not hurt as much so I’m confused? I feel like I have a full bladder like after 3 or so hours after last urination. And I feel like I have cramps but it’s probably my head messing with me because when I’m distracted I don’t feel them. Bloating is also something I always seem to have from diet and pms. I also had a brown discharge last night but it looked older and possibly could’ve been from gas. But I have been getting a lot of utis as I am recently sexually active. I’m worried mostly because it was my “most fertile” day. My period is due on the 15th by the apps calculator but my last period was apr 17th. Obviously my period has not been missed but I still freak. I hear you need actually insertion but I read other things on this app and see that you don’t need it apparently. Just some reassurance would be great. I am going on birth control on may 27th so after that my anxiety should decrease. But it’s just every little thing my body does worries me and I can’t help but think the worst. Someone please just tell me I’m a crazy person lol I’m 19 and don’t want to go through an abortion
