Should I go to the hospital?

Since yesterday I’ve been having these cramps/urges of feeling like I have to poo, but when I try to go nothing comes out and then after a little bit of trying the sensation goes away (sorry a little TMI). Two weeks ago at work I had two real contractions after speaking to my doctor and figuring out the pain that was going on in the moment, but nothing happened again after that. I’m only 35 weeks so i dont know if this is normal or maybe I’m backed up. I did go a yesterday morning, but then I had this feeling after and later on in the night. I googled what was happening and people were saying that it’s contractions so Im a little worried, but I really don’t wanna make a trip to the hospital and look like an idiot.
