i took 3 at home pregnancy test that came up positive. a couple came up negative. i went to the doctor and did 3 blood tests and they were all negative. i have missed 2 periods and fixing to miss my 3rd one in about 2 weeks. when i took my first pregnancy test i was only a few days late. but now i am really late. could i still be pregnant? i have never missed any of my periods before. i have been late before, but just by a week at most. i am so confused...has anyone ever had this happen to them. if so what did you find out, what did you do? Thank you for your time reading this and you help in advance.
