TTC- no luck yet

Month 7 of TTC and I feel like it's my fault that we aren't pregnant yet. :( how can we go from getting pregnant so easily, going through a pregnancy with no complications to a miscarriage in February and now still having a hard time conceiving :( 
I'm beginning to wonder if this <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> is even working because for 9 months I have been tracking so it should know my routine and we have been having sex every 3 days before and during my fertile window and nothing. 😡😡😡😡 who else's cycle is 32-34 days? Please comment below what days you ovulate I'm having a hard time figuring my cycle out. I know they say it's as easy as checking your CM but it's not for me. HELP!
