Needing help and ideas

So I’ve been taking opk tests the past few days, no took another tonight and took the others out, I noticed my opk from yesterday was dark. No my cycle has changed on glow I don’t know what to do, did I make it or missed it, opks go down in ordered top two from today, darker one from yesterday and bottom two from the day before and the day before that, next two pictures are from my cycle before and my cycle changing. Has this happened to anyone? Can someone give me an idea please
