Early signs of labour?

[Cantthinkofausername1990]

With my first child i don't remember having any signs that labour was approaching. My waters broke at 38 weeks and I knew that was it.
I'm 37+4 now and have felt really different all day today. Have crampy pains down low and feeling loads of pressure, more than usual. Also think I may be leaking waters very slowly, seem to have slightly wet underwear but no thick discharge.
Do you think this is a sign labour is near?
I'm due to have a sweep in the morning so will be seeing midwife and consultant then anyway but interest to hear others first signs of labour.

With my second I had backache all day followed by tightenings in the eve (no much pain with the tightning) by 10pm the pain came and had him by 7am the next morning tbh I had no idea I was in labor till the pain started at 10pm lol with my first I had a heavy bleed and kept in hospital till I had her 2 days later
