Hopeless venting

So here's my story. My husband & I had our beautiful little girl in May of 2011. I immediately had the doctor put the mirena iud in. In august of 2013, I had the mirena removed due to wanting baby #2. We found our we were expecting in end of sept of 2014 after 2 cycles of clomid. Then shortly after in November, I miscarried at 8w 6d. So here I am 18months later still trying to stay strong but it's getting harder. I'm going on my last round of clomid.
