Just so lost

So I don't use opk like I should cause I tend to take breaks sometimes. So I have use opk for the last few days and use on the day glow said was my highest chance but I had low fertility on that day. Haven't seen a peek yet. Glow pushing my period further and further back. Now I'm nervous  I'm not ovaluting normally now and that is a problem. 😩😩 I really just want to give up. I turn around somebody pregnant but me. Just tired of trying now.
