Brown discharge. Worried.

Kristie
Trying not to freak out, but brown discharge has started! I have had two mc and they usually started with some color discharge. It's just a little every time I pee and I don't have painful cramps, just a little pinch on my left side every now and again. I'm only 5w4d but I haven't had my first ultrasound yet. Eek! Have any of you ladies experienced this who have a history of miscarriage and gone on to have a baby after? I'm trying to stay positive!
