32 weeks/Light cramping

Bek
Hey y'all! I went to the doc yesterday and the nurse asked me if I was having any contractions, and I did tell her I've been having light period type cramps randomly. She didn't seem too concerned. 
Does anyone else who's 32 weeks, or around there, have slight cramping? It almost feels like period cramps, but not as severe and totally random. My baby is in the head down position as of yesterday. 
Is this what your body is supposed to do before the mega contractions happen later on? I've also had stomach tightening which I assume are Braxton hicks. It's tough to know what you're feeling when you've never felt it before!
