Real deal or no?

So since 8 last night I’ve been having period like cramps that wrap around my belly. They only last 30-40 seconds for 30 minutes to an hour total. And they come every 2 hours. They get worse when I walk. I’ve only ever felt pitocin contractions. So I have no idea what is the real deal or not. I may try to pump a little to see if the get closer together and stronger because this is quite annoying.
