I had brown discharge and even bled when I was around 6-7 weeks. Now, I'm 17 weeks dont worry its normal in the beggining. I went to emergency room and it was a waste of time and worry.
I have cramps to and im 8 weeks also. But I have no discharge. When my sister was pregnant she had the same problem and her placenta was ripping/ detaching its self she had to go on bed rest but it was fine after a week
