Metformin and Synthroid

Michelle • Im 30 years old and trying to conceive number 3! I had a tubal reversal June 1st 2016. Miraculously we conceived the first month and it ended in a miscarriage August 16th.
I've been on metformin for about a week and Synthroid for 3 days. Has anyone had any success becoming pregnant taking these? I had a tubal reversal done June 1st and miscarried August the 16th. I just feel like it's never going to happen and adding all these medications may prolong the process...but my hormone levels need to be better balanced :-\
