Can strep throat cause a late period

My period was supposed to start 4 days ago. I started feeling like I had a sore throat about 5 days ago. Last night I noticed white on my tonsils. So I’m making a trip to a walk in clinic today. My period hasn’t came though. I’ve had cramps for about a week which is normal for me before it comes, but now they have stopped. I’ve taken 2 pregnancy tests, one on 1 day late and one on 3 days late both negative. I don’t feel like I’m pregnant. I’ve had 3 babies so I’m pretty in tune on what it feels like. Has anyone got sick like this before and it delayed their cycle?
