9 weeks pregnant- brown discharge

I guess I need to hear stories of people having brown discharge and everything being okay.

I'm 9 weeks pregnant and have been having such cramps the whole time. They do get painful (today they are). I had an early ultrasound due to these cramps at 6 weeks. Everything looked great and baby had a heartbeat.

Today my two year old son and my husband have the flu. I'm not feeling 100% myself, but much better than them. I went to the bathroom and had a tiny bit of brown discharge. I've been having lightning crotch the past few days too which seems so early for that!

So anyone have random brown discharge at 9 weeks and have everything be okay?
