I am currently on the pill. My periods always come during the 4th week on wednesday. This month, I had bad crampsand backache (which i never get anymore) and bleeding this past friday, which lasted until sunday morning. Today i am supposed to start my period and nothing came. I did miss 2 pills during the month and had some of the "classic pregnancy symptoms" (which could of been just me getting sick) during week 2. Should i call my doctor? take a test? any help is appreciated!
