Hi Danielle

I'm at a similar stage of pregnancy to you and had this happen to me a couple of times a few days ago - it was like a sudden gush of fluid (not really enough to go through my clothes - enough to wet my undies tho) but it definitely wasn't urine. At first I panicked that I was leaking amniotic fluid but it didn't happen again so I stopped worrying about it. One thing I read is that when you do have a leak it is often more pronounced when lying down, so you could lie down for a bit and see if it happens then.
