Late period

I had a UTI about a week ago, and I finished my prescription last week. My period is 8 days late, and I’ve had sex during that time. But, I’ve still taken my birth control. My period was supposed to arrive whenever I got the UTI. I’m getting the pre period cramps, mood swings, and anxiety.

Could my period be late because of the UTI?
