Am I Pregnant?

So I can't use birth control because of the physical effects they have on me and condoms are a no go since I'm allergic to latex and things like it, also super sensitive in that area...

My fiance and I have been having unprotected sex for years now. We are getting married in October 2021 and I'm now 3 days late. I'm cramping and craving foods and moody. I thought damn my period must be coming, I'm super hungry and craving these random foods. Then ill get extremely nauseous if I havent eaten or if I eat too much or if I eat something I apparently didn't like. Im also having random heart burn attacks. Im probably picking up a pregnancy test but I'd figured before I did that I'd ask a few people here 😅
