I feel like I'm the problem...

My soon to be husband is in his 30's has two kids and wants more. I'm in my 20's and I just found out I have big ovarian cysts... Can this be the reason we haven't had any luck we have never used protection but have been having sex every day but my flow week for 7 months. I feel like I'm never gonna have a baby and its what we want more than anything... Is it my fault we aren't having luck???
