Not active, but maybe early?

I have been having consistent contractions since yesterday (39 1/2 weeks). It’s my first time and like most first time moms, I just want to know if it’s real! They started as normal tightening of the abdomen without anything. Yet, over time began to cause pressure in the front, back, and bottom of my pelvis along with back pain. I’ve had these before so I continued with life. I sat, laid down, drink water, and ate, yet they continued. We went for a walk, they continued.

What was strange was last night. Contractions for me are typically stronger at night. I will wake up to go to the bathroom, have one stronger one, and go back to bed.

Last night was different through. I was just having them, over and over. Like menstrual cramping and pressure. Then I started having a new thing, this sharp like pain at the top of my abdomen while having the pressure/cramping sensation.

Had that all night long, but I was able to sleep through it.

Will this actually lead to something or is it just my body doing what it does to prepare? I don’t want to pay too close attention if this isn’t going anywhere.
