Help! Is this normal?

Amanda

I'm currently almost 7 weeks pregnant with my first appointment on Monday the 17th. This morning I woke up to light brown discharge with teeny tiny little clot,only when I wipe. I've had the "achy" feeling in my uterus a couple times but nothing severe. My first and only pregnancy ended in miscarriage and I'm terrified of losing this one too! Is this brown discharge normal or should i worry?
