Girls, hello. First pregnancy. I have a question for you. Woke up at night to go to the toilet, as it became very bad to squeeze my sides, starting from the back and pushing into the belly. Went to the toilet, but it didn't pass. Not much walked around until it let go. Pregnancy is 38.3 weeks. Has anyone had this? Please tell me.
