Contractions real or fake??

Stephine

So this is my third baby, first had emergency c section bc she was being born with spina bifida and I was not supposed to go into labor but those contractions were not that bad. My second, never felt a thing. But now i am. My stomach keeps hardening quite often today and especially if I get up, it hardens and I can feel lots pressure in my butt and vagina and it makes it kinda of hard to walk. I know some people have said they were in labor and didn’t really feel much pain and others feel lots of pain. I just don’t want to be one of those people that call L&D; and and feel stupid cause it’s my third baby and I should know how this works.....but my belly gets extremely hard all over, goes away and comes back, if I stand it goes hard and I have extreme pressure from butt and vagina, sorry tmi but I literally feel like something is going to come out.
