Pregnancy test advice

My period is 5 days late and so I've just taken a pregnancy test which has come back positive. However, I noticed urine leaking through into the test window after i recapped it and put it down. Is this likely to affect the result? The control window has a line in it so I'm assuming it worked and the the cross for pregnant is very very clear. I'm just wondering if the urine leaking into it might have affected the result?
