It may be a uterine hematoma. (I know I spelled that wrong.) I had that with my first pregnancy. If it doesn't stop soon your doc may put you on bed rest for awhile. When it happened to me it was bad, thought I miscarried. I'm not entirely sure but it's my guess. Hope everything turns out for the better.
Spotting turned to red today with some very small clots...I went in to the dr. to get my labs drawn. We will see what the results are come morning.
Hey brookejmann, when I was pregnant with my second child I experienced the same thing. I went to the Dr and they told me that its normal, some women continue to have their period through our their pregnancy. I would check with your Dr, they might do an ultrasound to make sure everything is OK. As long as there's no pain with the brown discharge I think you'll be fine. Just so you know I gave birth to a healthy little big 7 in a half months later. Congrats on your you prenancy. I hope everything turns out ok
