Need your advice/opinions on cramps

Re

Please tell me your thoughts! I am nearly 33 weeks and have an appointment with the doc tomorrow. All yesterday and today I have had period like cramps, but very dull. A few weak Braxton Hicks contractions. These together have made my gut get moving... something that usually hasn't happened as frequently! No unusual discharge. I am a bit worried about the cramps, is this just my body setting up for labor in 7 weeks?? Other thoughts?
