Sounds normal to me. I was like that with my first and he was born about a week before due date, which isn't really early given that due dates are estimates anyway. I wouldn't stress over it. This time we still have 6 weeks to go and the bub is 2/5 down already which I thought was unusual for a second, but mw says all is fine and it might change its mind and pop back up yet... so it seems they do whatever til the day they decide to arrive or are helped to do so.
