I've heard from other moms to wear a pad, if it becomes drenched then it's your water. Or to lay down for a bit and to stand up and if you still continue to leak then go in. But for you being so far along I'd just call your doctor or labor and delivery.
I went in yesterday for leaking and contractions. Turned out not to be water.. But I swear I thought it was time ahaha every time I sat down or stood up. They did this test strip test. But I'd call your doctor just to be safe!
But I haven't had any contractions. Are there girls that get them and do not till the real thing? How much leaking does there have to be? Hopefully someone answers these questions because I have no idea lol.
It could possibly my be your water lleaking, I would call your doctor and let them know about it. As far along as you are your water could very well be leaking and you may go into labor soon so watch out for contractions! :)
