Contractions!?

Currently 37&4 and I am really over it I had my son at 37 Weeks exactly and was having contractions for a good week before giving birth to him and they were good heavy strong contractions and now with my little girl I haven’t felt not a single one so is it just me being more “use” to them or am I just not having them? I’m already 2 1/2 cm dilated and 70% effaced and I get some what of tightening in my stomach but I’m mostly baby so I can’t really depend on that it feels like and it’s nothing like I felt with my son so how do I even know if I’m getting them or when to time something that really doesn’t bother me? Anyone ? 😩 it’s just so different this time around so I feel like that’s why it’s frustrating lol
