show/bellydropping

Hi i was just wanting advice im 31weeks and pretty certain (i cant remeber seeing a show with any of my others or not like this as i was induced with my first and 3rd) i had a show 3 days ago (wont describe as TMI) but i will say microscopic sign of blood he has also become more active im getting BH but semi painful

i also noticed that i had dropped a large amount he has always been under my braline and is a fair way below it now and my need for toilet trips has increased hugely when i was at my MIL she commented that she thought i had dropped and that i wont make it to my march due date.I do worry because my boy was 10 wks early i went into labour at 23wks and heamoraged the drs stopped the labour this continued until i had him at 30wks

what im asking is are these signs of labour not being to far away i have a drs appt in couple of days and was going to talk to the dr then

Thanks
