Help please

Hello, looking for some advice on what is going on with my cycle this month. I got a positive LH test around cycle day 29/30 and I was supposed to ovulate Monday 25th July. (The app I use natural cycles is pretty good and is usually accurate for me however I do think my cover line needs amending and is too high for this cycle)

Any advice on what you think is happening would be appreciated 🥰🥰🥰
