31 TTC RAINBOW MIRACLE-Looking for some help

Ok so here is the situation. I use two different apps to track all data during TTC. I used an opk which said I ovulated on the 25th. For whatever reason both my apps are showing that I am ovulating now and I confirmed I didn't with another opk. Because my apps say one thing and the opk's are showing something completely different, how am I supposed to know when AF is due? Is it the 9th which would be a cycle of 28 days (average for me) or by Ovia and Glow which say the 18th? Any help would be great ladies. Been trying to conceive our rainbow miracle after a miscarriage early last year. 31 and husband is 33. 😬😖😶
