Brown spotting

Shauna
I'm 4w6d today, and started to have brown spotting yesterday. Got my hcg checked yesterday, and will get it checked again Monday to make sure my levels are rising like they should. No cramping, and no bright red blood, so I know that is good, but I still can't help to be scared. I never had spotting in my 1st pregnancy. Looking for some reassurance, thanks!
