When did you go in to labour?

Pictures from last week:

So bump has been head down for a few months now and has turned or come out which is good. Last week had a 4D scan they only got about 3/4 photos as he was very low and was offered a rescan, I saw midwife this week and she said his head is engaged about 4-3/5 and today I went back for my rescan and we didn’t get any photos at all as his head is too low and he’s facing down….

What’s the likelihood of labour being close ? Also if this has happened to anyone how long until you went in to labour and any signs to look out for ? Xx
