Am I in labor?

I literally have no pain threshold.. I could be in pain and not think anything of it ....today at about 5pm I got a pretty intense stomach ache so I went to go poop (sorry tmi) after I went i still had a pretty bad case of what felt like gas cramps so crampy I was kind of hunched over walking. This has happened before so I thought nothing of it, but about 2 maybe 3 hours ago I was sitting on the floor helping my daughter with her homework and my pelvis felt like it was being pried open with a crowbar it made me stop and clench my stomach ..that pain has subsided a bit but I'm still having the tummy pressure. The reason I ask is I didn't even know I was in labor when I had my daughter but luckily my neighbor was a midwife and she just so happened to come over and tell me that I looked flustered so she took me to the hospital and sure enough I was having contractions (didn't feel a thing) I know every pregnancy is different i just don't want to be laying here thinking oh its just gas and out slides my baby 😂
