Faint positives yesterday negative tests today

faith

I had a couple tests that had faint lines could’ve been indents or evaps but i retested this morning and they were negative .. so out of curiosity I took an OPK and I had a peak result. I haven’t had a peak this month but I have started a conception vitamin. I’m CD 19 I’ve never ovulated this late could I just now be ovulating? I’m so confused. Has this happened to anyone? Including my OPK this morning and my chart from this path month
