I have been off birth control since January. I’ve had regular periods since then until this month. I was suppose to start on June 6th and I still haven’t started, so I am now 11 days late. I have taken several test and they all say negative. I wasn’t trying with my first child and never really experienced this. Is this normal? Is it too early to call my doctor? Why have I not started yet? This is driving me crazy!!! Either I need to be pregnant or I need to start my period.
