Contractions

Last night I was all menstraul crampy. For like  five hours. Then they mysteriously went away, and contractions begun. They were consistent at about 3 min apart lasting for 20 seconds. It really felt like IBS pains. My body did this for 3 hours. But they weren't getting anymore intense. I read online to take a warm bath, if it's BH they will go away. So, after ripping into my poor husband, he told me "No, we arnt going to the hospital unless you are sure." I was furious. He drew me a bath that I sat in for twenty minutes and the contractions stopped. 

This is so frustrating. Is anyone experiencing the same thing? I was super upset that they stopped.
