Did my water break? HELP!!!?

im 15 an 8 months pregnate and due febuary 20th.last night i was taking a shower, and all of a sudden i felt a huge gush of cool liquid run inbetween my legs. i know for sure it wasnt the shower water. and idk if this matter but right before i got in the shower i used the bathroom and when i wiped it had a light pinkish tint, so i think my plug may have fallen out but i didnt see it in the toliet. i havent had contractions yet, just the usual little pain from the baby moving, so did my water break or did i have a random 'liquid' flow. could it be serious if it wasnt my water breaking? please help im going to the dr after school but i need some insight now
