my period is 8 days late, I took test too early and it was negative. I also caught a cold and fever a couple days later and breasts are sore and went to the doctor, just took a pee test and of course that was negative. I firgure I would wait 30 days then go back and ask for blood work and an ultrasound if it doesn't start by then. It's normally never this late going on 9 days could I be pregnant?
