I am 10 days late for my period, and they are usually like clockwork. I took 2 home pregnancy tests last week (different brands), but they both came up negative. I have very sore breasts (which I never get before my period) and several other pregnancy symptoms. I know that the HPT detect the amounts of hCG in your urine, and some tests are more sensitive than others, but if I'm experiencing these signs shouldn't it show up positive on the test? Could I be pregnant? If so, when should I test again? Please help!! Thank you and God bless ~Alisha:)
