Hard stomach?

Hey guys I’m not sure if this has been asked before but I’m 33 weeks on Sunday and I keep getting a super hard stomach a few times a day. Is this normal? I can still breath and everything through it but moving just hurts when it happens. I’ve also been having like period cramps. Any advice is welcomed.
