It has been nearly four weeks since my natural miscarriage and my doctor called last night to tell me that my hcg is still at 17 and that I need to go in AGAIN for more blood work. How long does it usually take to go back to normal? I'm just frustrated. Probably like a lot of you are. I was hoping I'd get lucky and ovulate two weeks after my mc and then get pregnant right away, but it's not looking like that's my path.
