Please help?

Autumn • My beautiful son born 5/26/19 💙🥰❤️😍
I have a really stupid question but I'm asking anyways. Took a hpt this morning but instead of laying it flat I laid it upside down and instead of dipping it in the cup for 5 seconds I did 10 (didn't read directions first oops) and I got a BFN but am now 5 days late. Could the results be inaccurate? 
Thanks for any help
