Frog or just pretend it's fine?

I've been knitting my second pair of socks following winwick mum's sockalong. it's my first time knitting a heel flap and I thought I finally had it finished and went to look at the next step, and realised that I've been doing slip 1, purl 1 until the end of the row instead of slip 1, purl until the end of the row. Should I frog or will I still be able to turn the heel just fine and have an extra reinforced heel? I'm knitting 2 at a time using a long circular needle
