need some help please........ FTM

Claire
Not quite knowing how I feel so looking for anyone who has maybe some previous experience for help. 
I went for a growth scan yest due to bump not progressing properly, currently 33+1, his growth has trailed off and the amniotic fluid has more than halved since last scan at 31.
I'm not due until Feb 9th but back for a fluid check next week and if things have decreased again then he may be here before the end of 2016! If not, back for additional growth scan in 2 weeks and he may be out then.  Obv they are trying to keep him cooking as long as possible but I just want him out n safe knowing he can get what he needs out here.
Maybe I'm being selfish but would appreciate some help on how to not have worried sleepless nights for what I think will be the longest week in my pregnancy so far!
