Should I go to the Doc?

Maria
Just wondering how long most women wait before they would go to their doctor to get a blood test? I am 5 days late, which I have never been late before for AF and have taken several PT and all are negative. I am super hungry all the time, certain smells get to me, my boobs are starting to become sore, and I have mild cramps off and on.....I just didn't know how long I should wait :/
