Miscarriage back to back..

I had a miscarriage on July 7th and bled till July 14th. I took an OPK on July 19th and it was positive. Got what I thought was my period on the 28th. Doctor asked me to get a blood draw to check my levels and see if it was a possible miscarriage again so soon. It's been 4 days and I am still bleeding. Has anyone had a miscarriage 3 weeks after the first one?
