Over doing it

I’m 31 weeks and I think I’m over doing it Iv just moved house so the last few week iv being painting new house and cleaning taking 5 kids to school then going up my old house moving stuff and packing and cleaning for 2 weeks iv never sat down for more than 10 min a day going to bed after 12 waking up at half 7 I’m worry all this work might bring my labour on early so question is has anyone went into labour early due to over doing it
