Thanks Lime & marcellus. I'm pretty sure its just normal CM, probably just a bit more than I'm used to. Its not really increased or gotten any worse over the past few hours. My midwife called back to check and said its probably just normal leukorrhea (which is the normal discharge we get in pregnancy) just a bit more profuse. I think what threw me was that it seemed quite suddenly so thin, but that is passing so fingers crossed its just been temporary. And bub is still kicking around, albeit once in a blue moon. I think he/she is having a hide & seek day.
