Calm my nerves please!

I’m 9 weeks pregnant today and my DH and I finally had sex for the first time in a few weeks (he’s been away). During all the fun we saw that his parts were covered in blood. Obviously that killed the mood so we showered and took a nice long nap. There wasn’t much on the pad when I got up but now moving around it seems to be spotting some. No cramping or anything. I’ve read this is common but I was just hoping for some reassuring words!
