I’m really scared hear me out

Nan

I’m 15 days late off my period I’m usually never this late at all maybe 2-3 days but never 15. I had sex for the first time without a condom and I’ve been really scared ever since. Stressed,anxious,not eating at all because I was so scared. I’m definitely having Pregnancy scare. I’m also really paranoid like at this point one little gas bubble scares this shit out of me. I’ve been sleeping late, kinda sore breast, stomach makes a lot of noises only at night though, gassy, more discharge then usual (wet/white) , headaches(could be from stress), and bloating. Sometimes after I eat I don’t really feel full like I could eat more could it be stress and just overthinking everything. I know how stress and diet changes can really affect your periods... could it be that and I’m just scaring my self/overthinking it?! Let me know PLEASE 😚
