Very confused?

So I took the first opk (top test) and it came out very positive within the time frame. I have very irregular cycles so I was scared it was to good to be true to a positive opk so I took two more using the same urine (the 2nd and 3rd rest) which came up negative. I also tested on the 19th and got an obvious positive but decided to test again today because my body felt off. What do I make of this? ☹️
