Hello, I my first birth control pack was Sprintec. I began having unprotected sex after the 3 weeks of active pills, during the placebo week. Then my pharmacy changed my birth control to Mononessa. I took those immediately after I was done with the inactive pills, starting on the Tuesday pill because it was a Tuesday. Should I be worried about pregnancy? My first day of inactive Mononessa pills just ended, and I'm supposed to get my period sometime today, but I'm not cramping or showing any signs of starting my period. I took a test (although it's a day before my period should be) and it came out negative. Should I be worried that I'm pregnant?
