Hey ladies so I need everyone’s experience on the different feelings of these. Like labor contractions vs Braxton Hicks ?

Also if anyone has any advice for me then please read my story :(

I woke up at 4am with sharp pain in my stomach it lasted a while like every couple minutes then go away. Eventually I fell asleep. I woke up at 11 with some more pain like uncomfortable hurt to stand fully up and some tightening in my stomach. Then it went away so I did some cleaning and it started back up again tonight and it hurts mostly in my back now and occasionally tightening but not really cramps. Maybe very mild ones.

Keep in mind I’m also constipated and I’ve been drinking miralax and coffee and lots of water for days and it’s not helping. So idk if this is just constipation pains or if there’s more to it ? Thank you for anyone who reads all of this and has some advice.
