I am 6 weeks pregnant and have spotting a small brown discharge...is this normal? no cramping, and i had a d&c back in jan and i was 16 weeks

It can be normal, bu: Spotting in pregnancy is very common, usually it doesn't indicate a miscarriage, but without a sonogram it can't be determined definitively. The D&C at 16 weeks - is more concerning, depending on the circumstances, you may want to see if you need a consultation with a perinatologist. Miscarriages at 16 weeks - are very unusual and may indicate another problem.
