If it helps at all, PinkPandy, my first AF after birth control was awful! Bad cramps, back pain, everything. Since that one time though, they haven't been that bad. Boo for the opks, Flueky! Keep trying. Still no sign of AF for me. I keep checking because the cramps are so bad, but nothing yet...I want to get excited because I'm never late with AF, but I could start later tonight or even tomorrow. Fingers crossed! !
