I have been on birth control for about 4-5 years now. On the week of April 11th I completely forgot my pill on Tuesday April 12th & took Wednesday's pill about 11 hours late but took the rest of the pills on schedule as usual. On Sunday April 17th I had sex & on April 25th I started my period. I was supposed to start my period yesterday, May 13th but have not started yet & I'm freaking out. Am I pregnant? I have never missed a pill before from what I can remember. Thank you!
