Last night as I was getting ready for bed, I went to the bathroom, and when I wiped, there was a decent about of dark red/brown blood on the tissue. Obviously I started freaking out and I got no sleep. I woke up every couple hours to pee, but didn't notice much going on.

This morning, I've noticed some light cramping, and the couple times I've gone to the bathroom, there has been dark brown blood on the tissue. Not a LOT, but still noticeable.

I called my doctor and I have an appointment for tomorrow morning, although they said if the bleeding gets heavy, I need to come in immediately. Does this sound like I'm having a miscarriage?
