I don't get it, help!!!

So this is our 3rd month ttc after coming off nuva ring for 2 years. I'm doing everything to try and get pregnant without going to the dr yet for help. I just started my period yesterday again, but I never had a day this month on my opk showing that I ovulated. Plus glow said i was due to start my period a week from now, don't know if that was right at all. Just feeling lost on it all. Any suggestions ladies?
