FTM - Braxton Hicks vs something more serious

Please no judgement and no “you’ll know, trust me”

How will I know when I’m in labor...

Let me start by saying, I have a high pain tolerance and I tend to allow myself to suffer when I shouldn’t because I don’t know when to say “enough is enough”

I just deal with it

I am only 34 weeks 1 day with my first. So far no complications.

For the last two days I have been having really bad stomach pains that are almost 24:7. I have had what I believed to be Braxton Hicks a few times starting about 29 weeks. But they don’t have time patterns and don’t last more than an hour a two and they are mostly back pains like you’d feel during your period.

This pain that I’m having now is the top of my stomach, it’s really really hard, and the only way I can describe the pain is if I were to not have a bowel movement for a month and was extremely constipated.

I definitely don’t have any issues going to the bathroom these days so I’m just curious if anyone can help me and tell me if this is normal or when I should be concerned
