Could I be going into labor early? 34 weeks

So since I laid down to do to bed last night, I’ve had this sharp stabbing (pulsating) pain in my lower right abdomen. I lay down on my left to sleep and after I was laying down for a little bit the pain got a little worse and was starting to hurt my back too. So I flipped over and it lightened up~ I fell asleep.

This morning I got up to pee, laid back down (on my left) and the pain was back. Flipped to my right, it stayed. Sat up, stood up, tried some stretches nothing is really making it go away.

Today I am nauseous and I have diarrhea. (Which isn’t normal, I had absolutely no morning sickness and I am on iron for anemia so I have been having bowel problems but not diarrhea)

Idk I could be over thinking this, but I still wanted to post and ask if anyone experienced this. I have had no spotting, just cramping. Online it says diarrhea is a sign of labor coming soon (48 hours) but he’s not done cooking yet.
