Flashing smileys 😑

Just started using glow on the 13th of this month, so I haven't really tracked much before then other than my January period. I got my IUD removed December 8th after having it for 5 years. This is my first month tracking with OPKs. Got my first flashing smiley on Thursday, but still no solid smiley. Did BD on Wednesday night and will again tonight. Currently on CD19. How many days did you have flashing smileys before you got a solid (peak) smiley? So frustrating! Lol!
