Hello ladies! So last month I switched from one type of pill to another due to the one making me sick. Well since I have been on the pill my periods have always came on the third day of the placebo pills, this month my period never came on the new pills. My partner never finishes inside of me and I took a test and it said negative. I’m still worried that I may by pregnant. Has anyone ever experienced a missed period when switching types of pills? Thank you in advance!
