I had a d&c on Feb 12th as the ultrasound showed no heart beat at 10 weeks of pregnancy and the baby measured 6 weeks. I had an usg earlier at 6 weeks 5 days, then also there was no cardiac activity. My homocysteine level is elevated (around 16 instead of maximum 13 units). I have been having biopreg-f 10D since d&C, but before that also I used to have folvite since June. When should I start trying to conceive?
