Can’t get pregnant.. or?

Hubby and I have been trying for quite some time now

I stopped tracking most things bc I just got tired of always being disappointed with a BFN

I used to use ovulation test strips and found that I ovulated every CD17-18 & we would always get busy around that time

My period would be on a 30-35 day cycle

Is that bad? Do you think I am the problem?

The test strips told me I was technically ovulating so I was just wondering if maybe they were wrong ?

If it shows that I am ovulating .. then why is it so hard to get pregnant?
