If you got them when did they start and what did they feel like?
My tummy used to get rock solid in my other pregnancies but no discomfort.
For a week or so I've randomly been getting a really tight tummy (can be top, low or both) and can almost feel something like pressure or a ball in my pelvis. Sometimes get a feeling like I can feel my bladder get squashed and therefore tiny and full, like a water balloon sensation. All goes away when the tightness goes.
No pain just discomfort and odd feeling.
I'm 28 weeks.
