Brown blood is old blood so it's probably just left over. The cramps are also normal. Growing pains. :) congrats!
Most likely normal. I had spotting like that from 6-10 weeks. If you start having heavy bright red bleeding with cramps then that is cause for concern.
I agree with other girls. Had it for over 3 weeks went in for a US perfectly healthy baby. Stay away from intercourse until it goes away for a week. My doc says completely normal. Unless it gets heavier. Try to relax. :)
Thanks everyone. I feel a lot better about it now. Can't wait to have the first scan it still doesn't feel real enough yet. So excited.
