I have been on birth control now for 4 years. I am super religious about taking my pill at the same time everyday & cannot recall actually ever missing a pill. On Tuesday April 12th I completely forgot my pill & on Wednesday April 13th I took my pill about 11 hours late. I then had sex on Sunday April 17th & started my period on April 25th. I was supposed to start my period May 13th but am now 4 days late. Am I pregnant or am I just freaking myself out? I know it says for the combination pill you have a 12 hour grace period before it's considered "late" but I'm still scared
