M.C.
Go to the ER.
I had a similar situation. When I finally went to the dr. and explained what was happening she read me the riot act. 'Do you realize you could bled to death? The fact that you are sitting here functioning is shocking to me'.
She gave me some medicine, put me on an iron pill, scheduled some tests, and sent me to an GYN that saw me 3 days later. When I told him my situation his response was 'Do you realize you could bled to death?'
Go to the ER. Now please.
