I'm going through the exact same thing. I usually get my period within 1-2 days after stopping my birth control and it's already been four, almost five days since I stopped taking my pill, and still no period. This is really unusual for me. Birth control is also the only method of birth control my fiancé and I use, so I'm thinking I may be pregnant. I've been having really sore breasts all this week and I usually don't have any PMS symptoms.
i have also been on the pill for over a year, and i have the same question as you do. my period is very regular, and i take my pills the exact same time every single day. well, this month i was already on my 5th sugar pill with no period!! i did start later that day, but am wondering if i am pregnant or not?
Hey Im not saying this is the same in your case... but when this happened to me I was pregnant. My period is like clock work even when i was on the pill and when it didnt come on time i tried to ignore the fact.... but i was pregnant. but if i were you I would abstain from sex. not take the pill and take a pregnancy test in 2 weeks time. and then go on from there...
