Scared to have sex

I’m 5 weeks pregnant and to be totally honest im scared to have sex… when I was pregnant with my daughter years ago I started spotting after sex. I know it’s totally normal and it doesn’t mean something is wrong and it’s all because of extra blood flow in the cervix.. but I also know that if I see any blood no matter how little or what color im still going to have this paranoid voice in the back of my head and worry that something is wrong either until it stops or until I finally get an ultrasound.
