Movment.... When to be concerned

Ok ladies I am 36 &5 days my baby wasn't a very active baby my whole pregnancy but the last two days and really today she has been moving like crazy!!!! Like non stop my belly is just side to side to side I haven't done anything different, haven't had any extra sugar nothing, should I be worried could I be going Into labor soon??? Also an extreme increase in discharge it's a thin white cream and it always has like a liquid cirlce out around it could I be leaking fluid???
