I have a MC and had to get assist with pills 1/15. I have been hearing and reading that you can’t ovulate until hcg levels reach 0, is this true? As I went for a scan 2/05 and was told you can see everything fertile and ready in both of my ovaries and that I was ovulating then had blood work done for hcg 2/9 they were 19 and having some done today. I can’t get pregnant that quick and easy? It hasn’t even been 4 weeks help anyone with previous experience
