Worst morning.

This morning at 3:30 am i woke up with strong strong cramps, im a ftm so im not sure what contractions are suppose to feel like. This went on until 7:30am, the pain was so bad i threw up, used my inhaler cause my asthma was kicking in with every cramp. I called Labor and Delivery and my SO talked to them, they told me to start timing the pain, but there was really no way to time them it was just straight sharp pain like cramps but worse. They told me if it couldnt be timed it wasnt Labor its False Labor. So i never went in. The pain went away at 7:30 and i got to sleep but again i woke up at 9am with the same thing. Went on for about an hour and hasnt came back since. Has anyone had this happen to them? Did you ever figure out what it was? What should i do?
