Is this normal a day after AF??

(Pics included)

I KNOW it’s negative but hubby gets back on the 27th and according to Glow, O day is on the 27th and it was SPOT ON last month... I know it’s not dark dark but I wasn’t expecting it to be THIS dark given the fact that I just ended AF yesterday... y’all think ima have O day before the 27th? And also, do you get almost positives on OPK after AF?? 😕😕

Earlier today...

Last month... I ended AF on 3/20 and this was the progress. I started testing on the 3/23. Glow said O day was on 3/30 and it was right...
