So I take my pill at 7:40 each night and about ab hour later (8;30-8:40 give or take) I had diarrhea but it wasn't all all water there was bowel. I called the pharmacist about my specific birth control pill (Mononessa) and she said that diarrhea does not effect pills unless it is severe ( lasting for more than 24 hrs) so why does everyone else on the internet say it does effect it. She told me not to take another pill because it would be ultimately for nothing. I am on my 3rd placebo with no bleed yet I have had sex within the last two weeks.
