ovulation confusion (TTC) and worst breast pain

So I started using ovulation strips from august 2021, I ovulated on my 13th day of my last cycle in august.

Now in september I found out some weird CM discharge on my 5th day of september cycle till 8th day of my september cycle..I started testing for my ovulation on 10th day of cycle but it showed low fertlity uptil now. Any idea what is going on. From 7 day of cycle I am experiencing worst pain in my left breast and weird sensitivity in my nipples and i dont like it if my husband tries to hug me i am pushing him away All the time.

i am using clear blue advanced digital brand

I had one miscarriage on january 2021
