Help ‼️‼️ LADIES 📢❓

I'm having the most annoying cramps ever feels like AF in one spot on my right . I'm at work going through hell because of the pain & NO medicine to take . My period is due in 21 days & I ONLY cramp BEFORE I come on , so my period is out of the picture .  Me & my fiancé been ttc we hit it right on the nose this time 😁 . Did anyone anyone ever cramp before their BFP ❓❓
