Ugh... you can count from the time you germinated. Dont listen to bad advice. Too many people on here trying to change days and timing. Just say the number from "germination" so we are all clear.
Anyways yes it looks very small for it being that old still. In any case I cant see any preflowers so its still too young to tell. Some strains take longer to show their sex then others. Had 2 dawgs breath that pushed out pistils 4 weeks in veg while my jelly pie refused to have preflowers until I flipped the lights
Just wait a few more weeks and they will let you know
