I was told 3-4 mins spart lasting 45+ second
well this 2nd but with my first my water never broke but I was having contractions on my due date might I add they were 7 min apart but I wasn't sure since my water never broke I was 17 wasn't sure if it was Braxton hicks or whatever by the time I called my doctor and she told me to come in I know some people say if their contractions are not that close they just send you back home until when they are closer together. but anyways they took me that was like 8 in the morning and I had my son at like 2 that afternoon, I hope ive helped some,
