33+1 and looking for advice....

So I’m 33+1 and for the past 4 days I’ve been experiencing on and off period like cramps, I’m putting them down to being Braxton-Hicks from other posts I’ve read. However today I’ve woken up feeling like my vagina is broken! That’s the only way I can describe it! The pain and pressure in my pelvis/hips and particularly pubic bone is insane! I can’t sit, I can’t stand and I can barely walk because putting my weight on just one leg at a time is agony! Is this just a normal sucky part of being pregnant or something I should get checked out?
