I was told she was head down too then lazy week she moved so much it made me feel sick my pelvic pain disappeared then it came back yesterday she must have moved again and now I have an inflated vaginaWhen I told my midwife that mine had tripled in size she laughed and said sounds like baby is pressing on my vagina wall.
maybe it could be to do with some pressure, I know my baby is head down (not engaged) and charts so she has a large head so made sense to me
