pink spotting 😢

Jennifer
I'm currently 6 weeks 1 day pregnant. This morning I wiped and notice vvvf pink blood. I wiped agian to make sure I was seeing things! 
I'm trying not to panic but this is my explaination.
1. I had sex lastnight 
2. It's common to have light spotting?
3. I have no cramps at the moment
I'm praying nothing serious happens over the next few days 😫
