Trending OPK help

Je

Hello, I began to track for ovulation due to having a slip up a few days back.. couldn’t remember when my last period started but I know about when. I’ve tracked ovulation before with my previous baby and never had anything like this. Anyone have the same thing and still ended up pregnant? Could it be because I’m still breastfeeding? I don’t want a baby right now but we did plan to start trying in about 9 months.. any advice or personal experiences are appreciated!
