Questions I’m unsure of

So I have a few questions.

1. I track ovulation and I was suppose to ovulate on the 15th of this month but I didn’t I didn’t get my positive ovulation test until the 17th, so with that being said I am suppose to start my period tomorrow but that’s based on me ovulating on the 15th will I start later since I ovulated later?

2. I dipped 2 test in the same urine and 1 was faint positive and the other stark white negative to me so was the positive one a fluke or has any experienced this?

Pictures for reference

Top one is positive in person bottom one negative

This is the positive one tweaked

This is the original positive one

ovulation tests

period tracker

Anyone’s opinions, do you think the positive one is real and that I’m pregnant has this happened to you and been pregnant???
