Hi, I'm 26 years old and 15 weeks pregnant and I have several gallstones, and yes it's really painful! I take 3 lots of paracetamol a day which is safe for the baby and I have had to totally change my diet. Its ceral and fresh orange 4 breakfast, ham bun and yoghurt for lunch, a healthy low fat tea, and crispbreads with low fat spread before bed. It is seriously boring but it is controlling the worst of the pain. I'm having my gallbladder removed after I've given birth, but unfortunately the doctor has told me today that I have to take a month off work to give my insides the chance to settle down. I had no idea that I had Gallstones till i was pregnant, but it's something I just have to cope with for the sake of the baby. I hope your sister is ok and that I might be some help. Emily x
