Ovulation while breastfeeding?! HELP

Me

My husband are I are hoping to get pregnant while I’m still breastfeeding. Our baby is 7 months old and plan to breastfeed til 1 year.

I had a period end of Feb/early Mar and not since. Negative pregnancy test.

Wanted to share my OPKs to see what you think - am I ovulation while breastfeeding? Idk why the app started my cycle day count over in May when I didn’t have a cycle but whatever.
