Is your Doctor aware of your pregnancy? Spotting is common in the first few weeks, like the others said and may be implantation bleeding. However, if its more than spotting I would definetly call and speak to your doctor just to be sure that your pregnancy is following the norm.
Best wishes for a full term and a happy healthy baby at the end!
At 8weeks its likely to be implantation bleeding. Nothing to worry about. If it were bright red I'd be concerned but a little pinkish/brown spotting is normal at 8weeks.
Congrats hun :-)
The brown discharge is probably old blood which was left over from last montj period. I woyldnt worry to much but if it starts to go pink like freash blood go and see u doc x hope this help
