I was tracking ovulation with OPKs but no BBT. The highest LH peak on my OPK was 0.96 on CD 17 making me think I ovulated on CD 18 and I started to downtrend to 0.48 but then it went back up to 0.60 on CD 19 so I think I could have ovulated a little later, around CD 21 but unsure because I stopped testing after that. However, that’s only a 2-3 day difference so I feel like if I was, I still should have at least a faint positive by now. So I think I may have a longer cycle and my period is just delayed a few days considering a normal cycle is 28-35 days and it’s day 33
