I just got my period yesterday, it was 8 days late because I took plan b multiple times in the past 2 weeks. I started tri sprintec recently, and this is the most painful period I have ever had. My cramps are bringing tears to my eyes, and they're so bad I don't even want to stand. Is it okay to take midol while on birth control, or will it affect the birth control? Open to any thoughts! Please and thank you!
