Watch soap2day. When filmmaker Megan Wennberg's period went nuts, she thought her Uterus was out for revenge because she was almost 40 and hadn't given it a baby. It turned out she had fibroids. Bloody Mess is a short, animated documentary following Megan and her Uterus (voiced by the always incredible Susan Kent) on a harrowing but darkly funny journey through the medical system to try and stop the bleeding.
