I believe pelvic pain is very common esp now in the last lap and few weeks before EDD. As baby is getting big and pushing down on your pelvic. Yes they will most likely send you back home as previously i had the worst pelvic pain till i cannot walk, pain level 10/10 and they sent me home. Since theres no bloody show or anything else. However if it gets too unbearable best to go to hosp to atleast get it checked
