[|Human|] I recently switched from Beyaz birth control to Tri-Previfem. I have not finished the first week of my new birth control, but i have already been having side effects that I am worried about. I have loose stool (not liquid diarrhea, but very soft stool) at least twice a day but never more than three times a day since i started Tri-Previfem on monday. I am worried that this diarrhea was caused by this birth control and that is also affecting the birth controls effectiveness in working. I had unprotected sex on the third day of taking this birth control. If i have been having regular loose stool, can i be pregnant? Before this birth control, I had taken Beyaz regularly and almost perfectly for about one year.
[|AI|]  Hello, Women who change birth control pill or use for the first time, more commonly get adverse effect for first 1-2 months. Birth control pill takes time up to 1 month to adjust with body hormones and give the highest protection. In this time period, some back up method like condom needs to be used for highest effectiveness against unwanted pregnancy. However, loose stool or diarrhea itself does not alter the efficacy of birth control pill. Your chance of pregnancy is quite negligible on 3rd day. So, don't worry about that. Take some probiotics and Chat Doctor.  Hope, it helps for you. Good luck.
