i’m actually so paranoid😬

so basically long story short, my ex came over about a month near 2 months ago and we had sex but didn’t use protection, i was so paranoid about it after. i waited 2 weeks for my period to come so i could stop worrying and it came on time and i came off on the exact time but i still felt weird in the stomach so i told my mum and waited about 6 weeks then got a pregnancy test and that also said negative but now i’m 3 days late on my period and my stomach still doesn’t feel right!!!

what should i do?
