Discharge and cervix!

Hey guys, so recently I've noticed I have to go to the bathroom a lot more frequently ( and yes I'm sure I don't have a UTI) but also I've noticed when touching myself I can feel that my cervix seems a lot bigger and more pronounced than usual? ( I'm short in that area so I can always feel it to some extent when touching myself or sex) I've also had VERY RUNNY white discharge, at one point I had to ask myself if I wet myself or if I was really horny lol! 
But this is not normal for me, normally my periods are irregular so I can't really pinpoint when I have hormonal differences through my cycle but I've never had them to this extent. What is this?
