Ouch the end is hurting

Michelle • 27 years old Wifey & Momma of a 3 year old. Currently expecting #2 in July 2015
Today my back and crotch are achey.! Got my crotch it feels crampy and sore like I pulled something but I'm sure it's just the weight of baby boy. And I swear I can't even think about nesting cuz my back just throbs. I have my 36 weeks appt tomorrow so I'm gonna vent all this to my doc. But ouch I forgot how uncomfortable the end is! I'm ready for baby boy to come out! Sorry little vent!
