Good evening everyone ? Girls, could you please tell me if you wore a bandage during your pregnancy? It's so hot in it ?, I don't even have any pain in my lower back or anywhere else. I don't walk that much, just around the house all day, and only for a walk in the evening. Therefore, I would like to know if it is mandatory to wear one?
