Okay, so I am 13 weeks pregnant, 14 weeks tomorrow, and I am perfectly aware that I am super skinny but no matter what I do I just don't seem to be gaining weight. I'm 7st 12lbs and am 5ft 4in so that leaves my BMI at 18.8 which is extremely low. I'm very worried that as a result of my low weight that it'll effect my baby. Does anyone know of anyone in my situation?? Has anyone been in my situation who has gone on to having a healthy baby??
