So when the ER nurse took my blood pressure, they used one of those automatic ones where it gets tighter and tighter.. almost like to the point your arms could fall off. Well, once they took it, I had what looked like a hickey in the same shape as the lines on the blood pressure thingy. Does this have anything to do with me being pregnant and pumping more blood ?
