Braxton hicks contractions and nausea?

Do your braxton hicks contractions make you feel nauseous? Last night as I was laying in bed, I was tossing and turning because my stomach was hurting so bad, I really felt like I was going to throw up. It made me nervous. I don't know if it was from the contractions or if I am getting sick. I didn't have any other symptoms though, so I don't think it's a stomach virus. Should I go to the doctor? I'm 28 weeks.
