What does it look like if your water is leaking in pregnancy?

So on sunday when i went to the bathroom, i noticed a glob of goo in my underware..sorry tmi. it was kinda clear kinda yellowish...then ever since then i feel like i keep wetting my underware. like i feel like i have to pee but cant go. and then this morning, thursday, i woke up with bad stomach cramps that kinda felt like diarreah. which i had yesterday. but these cramps felt a little different. and when i went to the bathroom i peed, then every few minutes after that i would pee a little again. when i looked in the toilet it wasnt yellow, it was clear like i didnt pee or anything. i am almost 35 weeks with my first and im not sure what is normal and what isnt, but when i go to the bathroom my underware is always wet a little like a quarter size amount. i have been to the drs. a few times because i felt discharge and they just say its mucous. but then it goes away. and this is more watery. i have a drs appt tomorrow and i will ask but until then...any suggestions or feedback would be awesome!
