anybody else have any big changes right before they went into labor? the last two nights I have completely slept through the night... I normally wake up at 1 a.m on the dot to pee and eat... and tmi but I have had diarrhea all day today.. and people keep saying it sounds like labor may be close. so what were some changes you ladies noticed?
