If you're concerned about it I'd definitely ask doctor. I had this happen to me recently too though...it wasn't a weird color but just much more thick and a lot more of it....my midwife told me it was just from all the hormones and the baby probably pushing down on the kady parts forcing more of it out....and I'm 39 weeks now and it has gone back to normal.
I would still see a doctor just to be safe
Not an infection, it's barely green & has no smell. It's more yellowish, like a creamy color.
Well if it's greenish if go get checked out by a doctor, it could be an infection!
