i'm concerned because I missed my period. I take the pill and didn't miss a day, although I was about an hour late one or two days this month. I also broke my leg this month, and was very careful about making sure none of the prescriptions I got would interfere with my birth control. If I weren't taking the pill, I wouldn't be concerned because i've had an enormous amount of stress this month. But, I didn't think stress and emotions would cause you to miss a period if you were on the pill. If anyone has any insight into this, whether or not trauma like a broken leg can cause you to miss a period even if you're on the pill, I'd be very grateful.
