I have been in pain all day and it has been 3 days now sents I have been like this! I am also getting to where I am getting weak! I have been throwing up! But my back and my lower right side is killing me and I am getting to where I can’t even get up off of the couch! I am 14 weeks and 5 days I don’t know if I should just go to the er or wait u til my OB appointment witch is Tuesday! But that is like 5 days away! I am already going already on 3 days! I also this is my third baby by like today I have not felt my baby move but yesterday and the other I felt my baby move but today nothing so I am getting worried and also my pain is like a 9 on a 1-10 pain level scale
