Waters breaking or squirt? TMI sorry in advance

Sorry for TMI. Tonight me and my husband decided to play about. Being 33 weeks and very big I find it hard to have actual sex so I have a vibrator. We used this and I thought I squirted (I've done this before pregnancy and it all felt the same). But looking back there was much more fluid than normal. I've not had a show or plug or any kind of pain since it happening and had no other leakage down there. Baby is moving as normal. Has anyone else experienced this? I don't want to ring labour ward if it's just squirt as it's embarrassing to explain. Liquid was clear as far as I could tell (grey sheets on bed) and didn't smell of anything.
