Hi Moms! I’m having pretty bad pain in my lower vaginal area. Almost like a menstrual pain & lots of pressure. Walking is even more painful.. Had an appointment today & the doctor said I’m really thin for how I should be! ( 34 W & 5 D ) what should I do? Being urged to go to the hospital but I don’t want to go for no reason, what would the hospital do?
