my sister is 20 wk and just had her 20 wk scan, doc told her there is only 1cm of amnotic fluid. they have told her he is growing fine at the min with a strong hart beat but with no fluid hes lung will no grow properly, they are giving her a scan in a wk they say if the fluid has no come back see will have to think about having the baby hart stop and she would have to deliver him or she can take the risk and carry on with the pregnecey. this wk is going so slow waiting for that next scan, will the baby have a chance to surviv if she carrys on? if anyone can anwer plz do.
