Ovulation confusion

[MrsPicklesonSmythe]

I'm wondering about these phone apps. I'm using PD which says my ovulation day should have been wed 24th but Ovia says it should be yesterday/today. One step opk seems to have shown negative today and yesterday but we were away before then so no idea.
We managed a few times while we were away a few days leading up to wed but that was it. Do you reckon they're accurate? Reckon there's any chance?

Wjst cycle day are you? I found ovia put my fertile week bang on 2nd week up to day 15ish going off a 28 day cycle, however according to opks I didn't actually ovulate until day 16/17 so I think they tend to generalise and go off what should be the norm.

If you dtd in your fertile week you should still be in with a good chance x x
