Bleeding after sex?

Me and hubby are pregnant with baby #2. And I know bleeding after sex can be normal but I can’t remember. Me and hubby had sex in a new position and I was bleeding when I went to restroom after, and a couple of more times after wiped. It’s a red color. Can anyone give me some advice? Is it okay to be bleeding red for a little while after you go to the bathroom after sex? I’m terrified. I’m almost 20 weeks pregnant
