Pregnancy complications?!?

okay so here is what i have been going through for the past three days i feel hungry all the time and it seems like no matter how much i eat im still hungry i just cant get full and i have been having heart burn so bad tums are my best friend but i cant keep taking them every 30min!. my head has been hurting non stop no matter how much meds i take i have been slowly leaking clear fluid and the past two days it has been the clear stuff and some very white thick stuff not really smelling so great i have been feeling sick a lot also along with tiredness all the time and it seems like i cant do anything without being out of breath even sitting on the couch at times and starting today my lower vaginal area you know where the baby comes out lol has been very swollen and last night i had this really bad cramp above my bladder and a few crampy feelings above my uterus and on the sides im only 31weeks so i dont think these are signs the baby will be coming soon i had my son at 39weeks no complications but i also didnt start leaking from my boobs until 34weeks or so with him and i started leaking at 27weeks or so with this one has anyone else gone through this?? is it normal? im going to contact my dr. in the morning im just scared shes gonna give me bad news!!
