Dull Lower Abdominal Pain


I just start TTC this month and I always used condoms before this because I couldn’t be on birth control. Ever since having unprotected sex I have had this dull pain in my abdomen. Anyone else have this? I have googled so much and can’t find anything. It started after the first day ttc which wasn’t in my fertile window (more like 2 or 3 days after my period).

It has been this consistent feeling even on days we don’t have sex.
