Miscarriage

Had a miscarriage July 6th. Been going to the Dr weekly for hcg blood work since to make sure its going down. I was 7 weeks 3 days at time of miscarriage. I thought last week I was for sure down to zero. Took a pregnancy test at home Saturday and it came back negative. Had follow up today from all the blood work Dr said last week I was still at 107!?? Did one more vial of blood today and I'll know results tomorrow. Got the green light to try again. Dr also gave me a prescription to take with my prenatals just wish this was over so we can try again. Took 7 years to get pregnant this last time
