Stopping tri-sprintec

Katlyn

Hi,

My husband and I recently got married and we’ve been having intercourse frequently in my fertile window(he doesn’t pull out). I just got off my birth control 5 days ago as of today and I have had horrible cramping throughout & now some bleeding. My period isn’t due until the 16th since I just had it. Can anyone please offer advice, I’m only 22. ????
