10 weeks still having brown discharge!!!

Emily
I've went to two early appointments the last one at 7 weeks and saw the heartbeat both times! I've been dealing with this odd brown but not brown discharge since i found out and last week i finally had none! Then I just got a weeks worth of it last night I've never had cramping or anything red...it almost lookes like a light mustard color I've had a pap and no infection...just frustrated and confused my next ultrasound is May 10th and I've already called about this I can't keep calling :/
