spotting 5weeks 2 days

So I had a little spotting today. It's kind of freaked me out a bit, but there was no cramping, no feeling changes that I could detect and it was SUPER light and didn't last all day, so I kind of didnt think to much of it. My boyfriend and I had sex tonight and made my spotting was worse, but still light spotting and cleared up the more I wiped. Has anyone had any experience with this? It's both of our first kid and it made us really nervous. 1st prenatal appointment is on Friday, so I plan to bring it up then. All opinions are welcome!
