Have an ultrasound coming up next week. Have just received instructions in the post. No food only clear liquids after 8am..... will be famished but doable. Told to drink 1 litre of water before the ultrasound to ensure my bladder is full. I have a pelvic floor which is pathetic at the best of times , in spite of all the exercises . I honestly think that if I drink a litre of water I will wet myself before or during the scan ! I shall be mortified if this happens. I can't do it .... I just can't. Help !
