Birth Control and Diarrhea

I am currently on Loestrin 24 Fe which I take every day at 12:00 noon. This past weekend, I had diarrhea Saturday night, and then again Sunday night. Would this have effected the absorption of the pill?

Thanks so much for your response. I have one more question. My boyfriend and I had sex 5 days ago. I am on Loestrin and he also used a condom. Some pre-ejaculate may have come in contact with me before he put the condom on. Is there a pregnancy risk from this? I have had weird twitches in my lower abdomen and nausea on and off.

Any weird twitches in your lower abdomen would not be a sign of pregnancy (or other symptoms) from sex 5 days ago. Pregnancy signs do not happen that fast (it is a misconception that a woman is pregnant at the moment of sex...it actually takes 10-14 days!).

If you are using your birth control pills consistently and correctly, they are 99% effective at preventing pregnancy. If your boyfriend used the condom consistently and correctly, they are up to 98% effective at preventing pregnancy. The chances of pregnancy are very, very slim when using this combination of birth control (we can't say there is no chance, because nothing is 100% effective).

Hi cmm1988

Thanks for your post!

We just answered a question like this recently - there should not be an issue with your birth control, especially since you took your pills at midday and got diarrhea at night. While there has been some mention of diarrhea affecting birth control, it seems it would have to be constant/chronic. The only worry would be vomiting within a few hours of taking the Pill, so you should be fine.

I hope you feel better soon!
