Frustrated

Liz

So here is my story. Got pregnant in April and found out around 8 1/2 weeks we had a MC. Then waited until first period and boom got pregnant again in the middle of June. Tested levels and they were going down so again another MC. Our dr said to wait until getting my period back, but my husband and I took the whatever happens happens approach, well got a positive and blood test to confirm last week. But again yesterday I had blood and my levels were going down. So another loss. Anyone experience something like this and eventually have a healthy pregnancy? Getting very discouraged.
