question: i missed my period and took 3 pregnancy tests, whicChatDoctore back positive. a week later my period came with abnormally big clots and white/greyish tissue. i suspect im having a miscarriage. it has been 4 days since i started bleeding and i m still cramping and passing clots. do i need to go to the hospital if i were only 3wks pregnant or will it just pass?
