Prayers please!

My husband and I have been trying to have our second child for a year and a half I have endometriosis and I've had 2 miscarriages, and 2 surgeries all within a 6 month time. I was diagnosed with MTHFR, a blood/gene disorder. I found out Friday we are expecting again, I'm so scared. My last pregnancy was in May 2015 and it ended with a miscarriage. We could really use prayers right now for a healthy pregnancy! Thank you!
