is this positive or no? (I have pcos so the readings never get as dark as they should)

Amber • 29 • pcos warrior • mom of 7 yr old • miscarriage at 9 wks after 2 yrs ttc • just had our rainbow baby 2/2021🌈

this is cd 23, 14 (yesterday) and 15 (today). it looks to me like it surged yesterday. I have pcos so they dont always read quite right but yesterday was darkest since cd 11 when i started testing, and today its vfl again. does that mean surge? any help appreciated. prayers to you all ttc!
