I am having some pretty significant back and lower belly cramping that began around 3 p.m. It has only gotten stronger as the night has gone on, but I can't define a beginning and an end to each cramp like I thought a contraction would feel like. It feels like some pretty heavy menstrual cramping. I was so sure I'd know what labor felt like, and now I realize I actually have no idea.
Did anybody else feel like this before they went into labor? How long before?
