37 weeks today, and yes I have had bouts of this happen. The baby is putting pressure on our colon, just like it does our bladder. Not a fun symptom at all :/
I've never done that but the sneeze and tinkle is a different story! I'll be 37 weeks tomorrow. Like the above poster said our muscles are stretched and our control over our most intimate of things are leaving us. I have learned to wear a pad and always have an extra at all times. Feel better. Not much longer to go.
Sounds like you sharted. No big deal especially when you are as far along as you are because the baby takes up so much room and our muscles are stretched to the max already that we don't have the same kind of control anymore. Compare it to sneezing and peeing. Sometimes you just can't help it anymore. Feel better
