Next Steps after Miscarriage

I am looking for a bit of advice. I got pregnant at the beginning of this year but found out the baby stopped growing at 6 weeks. I had a D&C at the end of February and waited the recommended time to try again. It took me 3 months after the D&C to have a period which worried me. It was really heavy. After that I hoped to get on cycle to start tracking again. But after that 1 period after the D&C I have not had a period in the last 2 months. I got blood work done 2 months ago and my doctor says my estrogen is a bit low. Im frustrated because I'm not sure if I'm ovulating since my periods are out of whack! Any advice or someone going through this? Is Clomid the next step?
