LaLa 💔5MCs👶🏽🙏🏽🌈
I had a positive pregnancy test on a Tuesday, I started bleeding 2 days later assuming it was a miscarriage. 3 days after bleeding I had bloodwork done. 
Monday -176
Wednesday-76 ( confirmed miscarriage ) 
One week later 
Tuesday -395
Ladies has this ever happened to any of you ? I don't know what to think . I have no pain ! Only pregnancy symptoms that I have is nausea and sore sore breast.
