HELP!!! Idk if i’m pregnant or not

Me and my husband are trying to get pregnant and I think that I am but I’m scared that my body just playing with me again. We had unprotected sex on the days circled in purple. I’m currently about three days late which has never happened before.

I’ve taken two pregnancy test on the 31st and they showed up negative. The same day I took three ibuprofen to help with the headache, about an hour later I had really sharp pains all over my pelvic area. It stopped when I lay down.

The last couple days since then I’ve had a little cramping pain(different than my period) and my breast have been huge and tender for a week. I currently do have an ulcer. I hope I gave enough information. Should I wait a week or two to take another test??? Thank you😊
