Nope, that's fine. And since that's the case, it probably is a REALLY big blood vessel.
I like to turn the eggs a quarter turn every few days. It helps with blood vessel development all the way around the air cell. Be very gentle with this one, though. The bigger the blood vessel, the easier it can hemhorrage.
