I've had discharge throughout the pregnancy - in fact, it was one of the first ways that I thought I might be pregnant. It's usually enough to make a mark on my underpants and thickish white. The past few days, I've still had this, but also had small wet spots on my underpants. Maybe the size of a golf ball. Is this normal? I would think if it were amniotic fluid it would be much more in volume, but I'm still a little worried about it.
