I M 25 Yrs Old, First Pregnancy, 32weeks N 4

I m 25 yrs old, first pregnancy, 32weeks n 4 days pregnant, my first question is I had leakage of water or urine for two days ,only once.my gynaec suggested dexamethasone inj four doses, 6ml per day for babys lungs maturity. Is it safe ,if I had only urine leakage instead of water... After two days ,today I felt FALSE labor pain n hundred punches by the baby after that. Anything you can suggest. M so afraid as my EDD is 5th Jan 2016..
I stopped taking my progesterone tablets by myself .. Few weeks ago.. As I had spotting when I was two months pregnant.
My gynaec told me yesterday dat I have vaginal infection, taking azithromycin tab n clingen forte . Will injecting dat clingen inside affect d baby.. M so afraid n worried... As its my first pregnancy..
Regards.
