So I’ve been really nauseous for a couple days and I have had a head ache I just went to lay down well my baby was moving weird so I turned on my back for 2 seconds to feel what was going on well I experienced the worst pain I have felt yet. Very sharp pain that ran through the bottom of my back into my hips and Vagina which the pain is now hanging out in my lower back and some in my hips anyone know what this could be?
