TTC after miscarriage from low progesterone

Surina
Hi everyone! I'm new to the group. I just had a miscarriage 3 days ago on June 30, 2015. I extremely devastated. I have been TTC for about 2 years and when I finally stopped trying so hard, I got pregnant. The day I finally confirmed at the hospital was also the same day I miscarried at night. I was about 6 weeks pregnant and doctors say I miscarried due to the egg not in its right stage when fertilized and also because of low progesterone. I am still bleeding up til now, but wanna TTC as soon as possible. When can I start to try again. Also has anyone used opk's and progesterone suppositories in their first trimester and actually made it through to a successful pregnancy after previously having a miscarriage? Any information would be greatly appreciated. Thanks!
