Accidentally Pee'd on Window of Test

I'm going to be getting an IUD in a couple weeks and they said we could schedule it after my next period to make sure I wasn't pregnant when I got it. They said it was up to me if I wanted to do a pregnancy test or not because I did miss my last one but that has happened before with the current brand of birth control pills I'm on. I took one and I accidentally pee'd on the window of the test. I definitely pee'd on the test end of the stick too but I'm wondering if that affects the test in anyway? 

It came out negative which I'm happy about obviously since I'm not trying to get pregnant. 

Thanks!
