Braxton hicks causes dizziness?

Meghan • I`m 29 years old and I have been married for 7 years and we have a 1 1/2 year old boy. Life is something grand!!
I have been having Braxton hicks once or twice a day, but it causes me to become dizzy. I never felt the tightening contractions with my first. In fact I didn't feel any tightening until I was pushing. I had the cramping pains. It's just weird to me I guess.
