Are these contractions?

Katie

FTM here with maybe a silly question. I think I'm having some contractions? My whole stomach will tighten up and be rock hard, and I have some period-like discomfort during that time. It's not painful right now, more uncomfortable than anything else. Is that what contractions can be in the beginning? Still a week and a half to due date 🤷🏻‍♀️
