Haven't had an epi, but did have a 2nd degree tear with DD2 (VBAC).

Part of this may or may not have been due to her size - I tend to think it was more about the fact that I was on my back which I did NOT want, but that's just how it worked out.

FWIW it healed really quickly, I was refusing the pain meds after day 2.

Fingers crossed you won't tear anyway!
