What does it feel like in the beggining? I have been having what i assume are contractions. But its in my lower back.. isnt really painful just uncomfortable and when it happens my whole stomach tightens up. I havent started timing them because at first i was just thinking im having back aches.. but they are off and on.. i have never had back labor so im not sure what to look for. It almost feels like my lower back is tightning up. I do not want to go to l&d unless its the real thing. Anyone have any experience with this??
