Stretch marks on eggs?

Checking on my egg yesterday, which is about two weeks from hatching if it's fertile, I noticed some "stretch marks" in the shell. One of the marks is wide enough that I can see a bit of membrane through it, but most are little lines. Thinking maybe this was a sign of overhydration, I opened the lid for a couple of days, but it didn't seem to make a difference. Is this bad? Normal? I can't really squeeze water out of the vermiculite, but it's wet enough to easily clump.
