Confused! This is my first month using OPKs, and according to them I ovulated on CD19. My tracker app has always predicted ovulation as CD14 (which explains why we’ve had no luck yet 🤦🏻♀️) as my cycle is only ever 28-29 days. So my question is, if the app says I’m 9dpo but my OPK would suggest I’m 4dpo when would my period be ‘late’?! App is still saying AF is due this weekend, but I guess I should probably go with the OPK? I don’t temp as we’re still quite early on in ttc so hadn’t got myself organised.
