Contractions?

Ive been having what feel like Braxton hicks contractions for almost 3hrs about 10-15min apart. They last 45-70seconds each time. I've also been nauseous and have slight back pain/period pain and abdominal cramping. I'm only 35wks. I don't want to go in for a false alarm and since they are so far apart I know I could probably wait until morning. Does this sound like labor symptoms? The contractions are not painful but i do have to take a deep breath through them. Every time it happens I get hot/dizzy.
