Timing and waiting

Currently, I am waiting for my midwife to call me back. I've been contracting every 5-7 minutes for nearly 2 hours with a LOT of abdominal and lower back pain. For some reason, I don't want to assume I'm in labor, but since my labor with Aiden was only 5 hours long....I probably shouldn't procrastinate on this too much. They may have me come in to be checked out in the office before any hospital trip would happen. So for now, we are just timing these puppies and waiting to hear back. I'll update when I know what's going on.
