Ok Ladies I Need HELP!!

Yvonne • I suffered 2 miscarriages but God allowed me to be a mother to a beautiful Rainbow Baby Girl!!
I am on cd13 trying the sperm meets egg plan I have using opk since cd10 and the line seems to be getting lighter not darker...Before I got pregnant last year my cycle was very regular I could even feel when I was ovulating even after my mc in December I swear I didn't miss a beat... period came in January and was regular and I could still feel when I was ovulating...This now my 3rd cycle since my mc and I have not felt one indication of ovulation and the test keep getting lighter...I have never missed ovulation or never not ovulated...Glow said today should be my peak day but my opk says negative and Glow was very accurate the last cycle...I don't know what to do
