thanks, the last scan was 4 weeks ago (this was scan #3) and with both the first and second scan they were pretty much the same size. she said it had only recently occured judging by the size difference. also she mentioned they may try doing lazer surgery to 'fix' the problem. we already have 2 children so are trying to stay positive and im keeping myself busy til the appointment to get my mind off it. Hard when i can feel one of them moving.
