Hi There. I Had A Natural Miscarriage 6 Weeks Ago.

Hi there. I had a natural miscarriage 6 weeks ago. I stopped bleeding completely 3 weeks ago. My HCG level was 13 last Friday and I started a very light bleed on the Sunday. My HCG level on the Monday were still at 8. Could this have been a period or was it remains of miscarriage? When am I likely to ovulate again? We are desperate to try for another baby soon as possible.
Thank you
Josie Graham
