Not sure what the hold up is with af. This is the 5th time I've tested negative since the first late day. I have been having light cramping on and off, sore breasts, sore lower back, increased appetite, headache this morning, you name it. I've been off bc for 8 months and my cycles have been pretty regular. My last period was a day early but nothing drastic. This is a whole 8 days late so it should show by now if it was positive right? Not sure if I should make a doctor's appointment yet or not.
