"i have just started this birth control, and have never taken anything else before. i started taking it the day after my dr. prescribed it, instead of waiting until the recommended sunday. i didn&#039;t think it would hurt anything; but i&#039;m pretty sure i was wrong there. i was supposed to start my period right around the appointment date. i then started 4 days later and have yet to end. that was nearly 10 days ago. also, i have never experienced cramps as badly as i did on this pill. i have never had children, but i swear i felt like i was having labor pains! the flow has been lighter than my normal period, just hasn&#039;t gone away yet. i am hoping it is just my bodies way of dealing with the hormones. guess time will tell."
