Real or false labour?

Ok I’m 37 weeks this is my third baby (I’ve heard they can be shifty lol) I went into threatened Pre term labour at 33 weeks but we where able to stop it I’m now 36+5 and at 12.30am contractions started they weren’t as painful as I know they can be but they where not bh they where between 5-3 minutes apart lasting about 50 seconds this continued until around 4.30am after calls to the maternity unit they advised I stay put until we got more intense and they where getting there but then amazingly I feel asleep I woke up at 6.30 got my dd off to school with mild contractions around 4-2 minutes apart and I’m sitting here at 9.30 in the same situation 😒 yesterday and the day before I’d lost some plug no blood and have been very nauseous and aside from how close my contractions are they are just not intensifying. Sorry for the long post but I’ve been having a very hard time this pregnancy and I want him out is this normal?
