Can a sinus infection cause your period to be 3 days late?

Hey guys! So I’m currently 3 days late, I took a test on day one but it was halfway through the day and I drank a good bit of water so I had to pee... but it was negative. I also currently have a sinus infection. And yes I’ve had unprotected sex all throughout the month. Haven’t kept track- we aren’t “trying” but not preventing either. So do you think the infection is what’s causing me to be late or should I test again?
