i hope you will be able to help me. i have been on yasmin for about a year, and 2 weeks ago i switched my birth control to yaz. i started taking yaz immediately after taking yasmin. i got my period after taking the 28 day pack of yasmin, and immediately started taking yaz the sunday after. i have been on it for about two weeks, but during the first week of taking it, i had unprotected sex. i am worired that i didn't wait enough time before having unprotected sex, and i am worried about pregnancy. if you could clarify, or help me with my situation i would really appreciate it.
