by the way,40 weeks today!
I'd call my doc and let them know and see what they say. When my water broke I was having no contractions or any pain but I could definitely tell it was my water breaking, it was just like a gush of water. Since I wasn't in pain or having contractions they told me to take my time before I came and try walking and stuff but my baby didn't come until 16 hrs later. However one of my friends who's water broke at home without any contractions had her baby 4 hours later. Everyone's different. Either way that baby's coming soon!
Yes go to the hospital. You can never be sure if it's ur water but anytime u r unsure or curious it's better to get checked just to be sure, because u don't want the baby to get an infection. It's hard to tell sometimes if ur leaking, but they say to lay down. U won't be able to tell if it is standing up because baby's head blocks it in. So go be checked just incase
