OK, immediately after I got my first period after having my baby I went on BC YAZ. So I've been on it for exactly 4 months. I should be starting my 5th pack tomorrow, and today I took the last of my reminder pills and I have yet to have a period. I've had sex twice and both times used a condom as well. I don't feel pregnant. On Thursday, I felt like it was coming with light cramps and such, but NOTHING!!!!!!!!!! No spotting, NOTHING!!!!! I'm trying not freak out because maybe it's something that could happen while on the pill? Has this happened to anyone before?
