I am 7 months post partum and still pee sometimes when I sneeze. Very normal stuff. Congrats on your soon to be little one!!
Your enlarged uterus is putting pressure on your bladder. It is extremely normal to have urinary incontinence during pregnancy, especially in the last few months. It is in NO WAY an indicator of labor or that it is time to give birth. It just means you have peed yourself. Try wearing a pad or panty liner to keep your undies dry.
i used to do it hun its nothing to really worry about but if ur still worried ring ur midwife
