Has anyone had to go into the maternity ward to be monitored for a day due to their GD??

Ive only been taking my BSL's for about 3 days and they are mostly average 7.... my ketones are up to +++ (does this make sense? cant remember the actual number as i just have to write down the +'s)

Anyway, was told today that i need to go in for tomorrow and they will decide what to do with me... is this normal? they didnt mention that this was a posibility when we looked at all the options etc....
