Am I finally starting labor?!

Kristy • Married the love of my life🤵🏻👰🏻4/21/18. Lost our angel baby at 11 weeks👼🏻 12/6/18. Had my rainbow baby boy👶🏻 3/27/20. Lost our 2nd angel baby boy at 21W3D 6/3/2022 👼🏻. Pregnant with rainbow baby #2.

I'm 40+3 today. I woke up around 6am and started feeling some tightening on my sides. They come and go but more regular than Braxton Hicks. I was able to sleep for a little but now that I'm awake i felt another pain in my lower abdomen. My pelvis really hurts it actually feels like I feel him in there. And I keep getting wet spots in my underwear. Is labor finally starting?
