I’ve been having some pressure 😩 and what mostly feels like period cramps

I’m 33weeks pregnant when baby moves I get this strong cramps it feels like he is sitting right on my vagina 😩🥺😕 is this normal around this time I don’t remember experiencing this with my other two pregnancies I’m taking two iron tablets a day now and I read that having low iron can increase preterm labor

Is having pain normal around this time??
