TTC after mirena

Katie
My honey and I have been ttc for about 18 months since I had my mirena removed in October 2013. I found out I was pregnant last Labor Day 2014 first day if my missed period. I started spotting that Friday and ended up having a miscarriage :'( I have regular periods, obvious signs of ovulation, and we have a very healthy and happy sex life but we just aren't having any luck getting pregnant! Has anyone else had trouble post Mirena?
