So stressed

I cannot believe how much you can really hype yourself up. I have been posting asking for comfort and advice on being pregnant because I have been super worried. I had no intercourse but my boyfriend came on my leg and I was super worried it got on my vagina. I have been told sperm dies when it hits air and that I have to have sex to get pregnant but I have still been anxious. I don’t know if it’s myself freaking me out and making me think I have symptoms or me actually having them. I kinda feel like I have been peeing more and a few days after thus happened I had period like aches but I haven’t had them since. i have also been worried bc I just feel this weird like feeling, not a pain but like a fullness feeling where my uterus is. I am supposed to get my period in 9 days. But I’m still anxious and I am only 15. I sound very stupid with this but when you are young you freak yourself out, at least I do. A girl just needs some comfort, love, and reassurance.
