my period has ended and

My period has ended and I had sex with my husband. He was rough of course. And fingered me rougj lol. I only felt pain mildly and told him to stop. It's been a few hours. I went to go pee and look down and there's blood. There's blood coming from my vagina. Not much. Just blood. I have an iud. If that concerns anyone. Is this normal? Or okay? lol I'm paranoid
