Hi me and my husband have been trying to conceive for over a year now. My periods are normally like clock work but this month I'm 4 days late. I've taken 3 tests all on different days including today but they are all negative! I have no symptoms other than my breasts hurting every now and again. It's like a sharp pain that comes and goes! Could I be pregnant? I really don't want to get my hopes up if I'm not!
