What should I do?

Last night was my last day of my period- my husband and I had sex; in the middle of sex he realized that I’m bleeding. It was kind of a lot. But I knew it wasn’t like period blood. This morning when I went to used the restroom there was blood in my urine.

Should I be concerned? Should I wait it out to see if it goes away in a couple of days? There is no pain when urinating or in the pelvic area.
