My sister is 6 months pregnant with twins, a boy and a girl. From the beginning of her pregnancy she has had a uti and has been on 5/6 different antibiotics and it has still not cleared. Is there any advice anyone has? she lives in Africa and so is a bit worried as twin pregnancy has higher risks. Her gyne has told her one baby is blocking the exit of the vagina with its back so she might have to have a c section and so they will have to give her an injection for the development of the babies lungs as it might be a premature delivery, has this happened to anyone? thank you
