Cycle adjustment after early loss


My cycle is relatively short, 24-26 days for the past 4 cycles (somewhat new to ttc). Well AF was late on the 10th and I got a BFP on the 11th, calculated to be 3 weeks and 6 days I think. Unfortunately I started bleeding on the 14th, and got a BFN on the 15th. Well there goes that.

Anyway, I'm not sure if the glow cycle tracker accounts for that? I entered the BFP in the log but I think it still counts that as an extra long cycle and idk how that will affect it's predictions. Does anyone have advice? I've never done OPK testing, maybe I should? I'm really new to all this and have been pretty casual up till now, but losing that bfp has made me much more determined. Any advice is welcomed ☺️
