bleeding after sex????

its not my first time having sex and its not my period and its not a lot of blood BUT after me and my boyfriend had sex today (which was a little rough but nothing we havent done before) i went to pee (prevent UTI’s!!!) and there was a littttle small amount of blood so i put toilet paper in my underwear just in case and when i got home like an hour later there was less than a dime size amount in my underwear but still some... is that normal? if it makes a difference i was like super wet during sex like way more than normal everything was sliding everywhere lmao so that was like unusual but not that unusual.
