I'd really appreciate any thoughts on this. I'm 6 weeks with my second and have had brown discharge since last Saturday. Had a streak of red on Tuesday so went to EPU and saw the sac and yolk but I was only 5+4 so they said it was too early for heartbeat. I've had constant brown discharge since. I remember having spotting with my daughter but not for this long. Anyone else have spotting that went on for a while?
