Leaking fluid?

I'm just looking to see if anyone else has had something similar happen.

Friday last week I had heaps of braxton hicks that actually were painful and consistent, along with dull back ache. I had a warm bath and went to bed. Woke up at 430am and still felt the same but almost like I would throw up.. from Saturday onwards every time I get a braxton hicks contractions I feel a lot of pressure in my bottom area, and also feel a very small leak or dribble from my vagina. I know it's not urine; it's completely clear with not really any smell. I'm almost 30 weeks pregnant and not once this pregnancy have I had any sort of discharge or anything my pants are always dry and so am I yet ever since Friday I've been getting dribbles of clear fluid almost water -like coming out of me. Not enough to fill a pad but it's still happening multiple times a day and it just dries then re appears on my pants again.

I'm more worried that every time I get a contraction it's doing that.

I've googled and have found it could be hind water leak which can dribble out or feel like bubbles in vagina (that's what it feels like).

Any body else experience this?
