Sorry if this is confusing but I need advice bc ttc is stressful 😭

So I bought another box of CB digital advanced OPKs and now I'm starting to second guess myself.... A little back story! Last month I bought the same OPKs because I HAVE NEVER HAVE A PROBLEM BEFORE. But I kept getting high results 7 days in a row so i tested it with water and it to came back high too. I was confused so I just said screw it and stopped testing. Come to find out i didnt ovulate until super late so I'm wondering if I did indeed just didn't ovulated yet and pee gets in the cassette tester and the water just dilutes it a little but not enough to throw a negative result. BECAUSE today the same thing happened. Day 3 of high results, which isn't out of the ordinary I think im just second guessing, but I tested it with water again and it was AGAIN high result. But I let it be for awhile and tested it with water again and NEGATIVE. Which okay that is what I want but I'm just even more confused now. So I found 2 old cassettes tested them with pee and both were flashing smiley faces signalling a high result! Whoo-hoo! But to test my theory I tested them in water too and again high results. I will test my theory again in the morning and test first with water and then with pee. So I guess what im asking is do you think the pee can get into the cassette enough that when I test DIRECTLY AFTER a high result reading with water its still detecting the LH hormone? Any other theorys would be appreciated! But do you think i should trust the high results? I just think it's weird 3 different cassettes gave me a high result, but who knows maybe its just a coincidence. Will be 2 years TTC in March and nearly 2 years since our MC. We wants our rainbow 2020! Please comment. TYIA 💖
