Still no ovulation!

I miscarried 3 cycles ago. I didn't ovulate the first two cycles, but I think I ovulated last cycle, right before my period came, but I'm not sure. Now I'm due to ovulate, and I'm still not showing any signs it's happening! My opk will show positive, and my  and cervix will get ALMOST to their fertile signs, but not quite. I restarted my FertiliTea, FertilCM, and FertilAid, hoping it will help encourage my body to get back to normal, but after two cycles, I'm starting to get really frustrated. Any suggestions?
