False labour at 40 weeks

Anyone else suffered a ‘false labour’ this far along? I’m 40+2 and was in immense pain last night having what I thought was contractions that were every 10 minutes lasting 20-30 seconds for about 8 hours and then they just died off and have left me with just a dull ache, pain when I walk or move positions and occasional cramping/tightening. Seems strange to false labour this late in pregnancy.
