They stopped , but I think they were contractions too !, the baby must be almost ready.
When I had contractions with my daughter, they felt like gas pains and constipation and the pain was unbearable before I realized what they were and timed them. My Braxton Hicks contractions that I have been feeling since last night feel more like the pressure you are talking about. I know contractions are different for everyone, so it could be the real thing for you, but I don't know. Good luck!
