Pregnancy

So I’ve been having sharp pain where you usually get period cramps on my right side to where it hurts to stand up straight and I hurts to lay down with my legs out straight I have to have them curled up and it feels like a lot of pressure would you guys go in and get checked I have a obgyn appointment on Tuesday so I would like to wait but I don’t know if I should go in sooner I was thinking a uti but I’ve never cramped this bad with one before I’m almost 32 weeks pregnant
