Progesterone suppositories after miscarriages!

Catherine
Hello ladies! I am currently pregnant due September 1st 2017. I got pregnant on my third round of clomid, first actual round being monitored by Fertility specialist. Whn I got my BFP (12 dpo) my Hcg levels were at 65 and progesterone at 8.4. This was on 12/22. I was immediately given two progesterone injections and started on vaginal suppositories. From 12/22 to 12/26 my hcg levels went up to 812 and progesterone is was 23.4. I suffered two miscarriages in 2015, babies stopped developing. I never had my progesterone levels tested. My fertility specialist believes this is the reason why I might of misscarried,because of the hormonal I'm imbalance and my cycles being super irregular... anyone had anything simple to this? I am doing well and feel like this time around is way more real. Who here has success after miscarriage with progesterone suppositories? Thanks girls this is my first post and hoping to make buddies who want support :)
