Misscarriage

Last monday just before noon i had bad pain in my stomach(not cramps) to the point of being curled up in pain till late afternoon then had an extremely heavey flow till the morning then was done. I haven't been to a dr but i believe i had a miscarriage. I would have only been 4 weeks wich is sad but kinda good cause after a year of trying it looks like things are starting to work again after having my KID out :)
