27 weeks gush of water

I'm currently 27+2. Today when I woke up I had slight back pains. I got up and took a shower and was doing my daily work routine. I was sitting on my bed and when I stood up I felt a little gush of water. I went to the restroom and in my panties was a wet spot about the size of 2 quarters. There was a little bit of white discharge. I'm pretty sure it wasn't pee as I had just went and it wasn't yellow it was clear. I was thinking maybe it was access water from the shower. Any thoughts?
