Lower & middle back pain, nauseous out of no where, had sudden urge to #2, think i'm having contractions but im bad at being able to tell, & baby is all of the sudden moving quite a bit more than usual. 36+2 weeks. Also my hips are aching in the front. Sound like it could be or no? I will add i was monitored friday night after being rear ended and was having 5+ contractions in an hour.
