Ovulate early???

Today is CD4 for me, currently I’m still on my period (it’s extremely light at this point). I took this opk for pretty much sh*ts and giggles since it’s so early into my 31 day cycle but it came up pretty dark. I know it’s not positive yet but is this normal? I wasn’t going to start <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> this cycle until CD10 but now I think I should do it sooner. I ovulated CD20 last month this is currently TTC cycle 2 so I’m still pretty new to all of this! TIA😊😊
