CM after ovulating? Please help

So this was my first time tracking my ovulation using OPKs. I miscarried earlier this month and when I stopped bleeding we started TTC right away. My lines went from dark, to darker (but not QUITE positive but so so close), to lighter, then very faint. Did I miss my peek because I was only testing once a day? Or didnt ovulate? Either way I’m starting to get creamy white CM. I know that usually happens after ovulating. Is it possible I haven’t even ovulated yet? Or did I most likely ovulate right after miscarrying and like I said, maybe I missed my surge because I was only testing once a day?
