For the past 8 yrs I have worn my short shirt weraing 9/10 sum 8,and all of a sudden in Oct my stomache start getting round the black line pops up(the life line my granny say) I hid it, then in Dec my Preacher told me I was pregnant and I told him I wasnt and he said yes u are.So I go to the doctor the urine sample neg.,so then I go for a blood test its neg.,I go for a ultrsound and they didnt see the baby either so I go tell my preacher and he said that I am,which my stomache is still growing I feel movement I am the size I was with my other two kids.My Pastor said that God is protecting the baby cause its a gift and a miracle,my husband is a minister also and he said that he dnt care what the doctors said I am preg cause my stomache is round and study growing and one of my friends that has a strong spiritual calling on her life said that she had a vision and God let her know that I am preg,so what do you all think?

i think you should go to the doctor! it could be a tumor on your ovary, that can make your belly appear round as if pregnant, or it could be something else medical, just get to the doctor and ask them to run tests. Goodluck i hope all is well.
