labor and gas.

Ok, sorry this is a bit gross. I've been having Braxton hicks off and on for 2 days now. I woke up about 3 am with pretty bad cramping, but also I'm super gassy. Had 3 fairly decently contractions got up, did stuff. Was still having contractions but less regular and lighter. Woke up this morning. Having them again, little closer together, mostly feels like gas. Am I crazy? Is the gas just making them feel a little more intense? I was 2cm and 50% effaced  yesterday at 9am.
