Where do you get contractions and what exactly do they feel like?

I am 37weeks and I woke up to some pains here and there but omg they hurt when they come! Some feel like cramps. Some feel a real sharp stabbing pain. I haven’t timed them but I’m guessing they feel as 10-90 seconds? And a few a hour

Am I getting lucky and contractions coming on?

Please save the picture and tell me where you had yours and what they felt like

How did they start
