Hello, I recently switched birth controls from Junel to Microgestin. Right after I switched, my period ended and I had sex using a condom and being on birth control. After the month of being on Microgestin I switched back to Junel; however, my period is now two weeks late. I've never skipped a period before, and I am wondering if this period miss is possibly due to the fact that I switched birth controls? PLEASE HELP.
