37+4 weeks pregnant , real early labour?

My midwife thinks I may have had my show last night I had some fresh blood when I wiped , for the past (currently ) 5 hours I ve had on and off pain , it s my third pregnancy and always suffered braxton hicks for weeks on end but this time had nothing it s been a really comfortable pregnancy but sometimes u can forget what u have been through especially as my youngest is 5 this year.

I ve been trying to Google what I can about the differences it s super hard to tell , I want to determine wether I m in my first stages of labour or im in for a suffering of false alarms , it says braxton hicks aren t consistent does this mean the contraction feels off like up and down or changes intensity as it plays out? Cuz these feel the same every time they appear but have gotten slightly stronger since they started and with slow early labour can the contraction times differ like u could feel them regularly for a while then maybe a bit longer between ?

I ve had a bath n it didn t stop them ive been relaxed all night lay down sat up walked a bit n hasn t changed much sometimes I do something that makes them worse or they set off more in a row . So any ideas? early labour ??
