Contractions or movement?

So all evening I've been having awful pain up in my ribs and my stomach gets hard most of the time as well I'm trying to figure out I know my baby is head down as of Friday and I'm 2cm but was only 50% effaced I have done alot of walking the past two days since then but I'm JW I've been explained from one provider I seen I should feel contractions basically starting at my ribs (upper stomach she said) and go down my belly. However the midwife I seen Friday says they should start in my back like menstraul cramps which I've had off and on but it's not been bad whatever I'm feeling up in my ribs and making my stomach hard sometimes is what hurts idk if it's her feet or contractions at this point any advice?
