Start of real contractions? Thoughts?

Starting feeling these around midnight but didnt start timing until around 2am.

I've been getting significant to strong menstrual like cramping with them along with tightening of my uterus and back cramps. Also feeling pressure in pelvis and rectum. Also makes it hard to breathe during one.

What do you ladies think? Could this be the start of labor? Or just intense b/h? I know they arnt within the 5-1-1 now but could this be very early onset of labor?

What do you think? Experiences?

(Bottom picture is when I started timing them)

**Circled bc these 2 were together**

I took a bath about an hour before they started to try to keep Braxton hicks away. Also chugged two bottles of water between 12am-1am incase they were b/h. Been laying on left side as well.. ? Wouldn't that have stopped them if they were false?

Sorry for such a long post and thanks for any insight you may have!
