Is this Braxton Hicks?

I’m having intense stomach and back pains but last 2 days I’ve had bad bellyache ( don’t need toilet) and period type cramps. A good few times a day my bump is going really hard too? The belly and back pain/cramps are near enough constantly. I’m 28 weeks today.

Also I’ve noticed my moods/stress and tiredness is coming back bad again is this normal?
