I've had really tender breasts about s week before I had my missed period but I thought it was normal symptoms I usually get before my flow.I've never missed a period and I've been on birth control for over 5 months. When I got a pap I was three days late and they tested me at 4pm in the late afternoon for a result. It was negative. Today I'm a week late. Should I take a test myself ? If yes ,which ones works best? What time should I take it? Has anyone else experienced this ?
