Brown discharge 8 weeks pregnant

A

I'm currently 8 weeks and 2 days pregnant with my first pregnancy. I just went to the bathroom and had brown discharge, enough to fill maybe a partial panty liner. This has not happened before. No cramping today but did have mild twinges last night. I called the nurse line and they recommend to watch it and if color changes or get a temp to go in but for now nothing. I'm so worried. Is this normal and any reccomendations from u ladies on what I should watch for? Please help. Very concerned first time mom to be.
