My water broke when I was 38 weeks pregnant and it felt like discharge I would have so much I would go through a box of panty liners every few days, so I couldn't tell the difference. I didn't feel right so I went to l&d and had it checked sure enough it was amniotic fluid. Always better to be on the safe side and get it checked.
Amniotic fluid usually has a sweet smell. I would call the dr just to be safe. Good luck.
low back pain is common. use a cold or warm pack. as for you leaking. i would take it up with your doc... and see. good luck!
water doesn't have a smeel to it...so that's one way of checking or if you put on a pad...does it get get full or no?...waters wont stop for awhile itl just keep comming...me personally i wouldnt know...my midwifes have broken my waters when ive been about 6cm dialated each time so i don't know what the water breaking process is like sorry but these are what ive been told my other mums and its what it says in my pregnancy book...hope this little bit of info helps
