ok, ive taken like 8 home pregnancy test then i went to an ob gyn to do one they all came up positive but very faint...the doc had to do 2 test but they were both positive...she told me that i should go back and do another one but changed her mind when i told her how many i had taken...well the other day i got curious and decided i was going to buy another home test and when i took it it said negitive so i went back to the doc and hers said the same...now i started my period but its very light and my boobs have been sore and getting bigger and my stom. is hard since i began to think im pregnant...help???
