They sound like BH contractions. Trust me, when it's the REAL thing, you'll know. It'll start out feeling like very bad period cramps. You feel a lot of pressure and pain in your lower back. This is will just continue to get worse and worse. With my first pregnancy, I didn't want to go to the hospital too early so I stayed at home as long as I could. By then time I decided that I had waited long enough, the contractions were so intense that I was crawling on the floor. I had had painful ones before, but NOTHING like the ones I had during the real thing. Hope that helps . . . . a little.
