Mastitis, should I wake baby for feeds?

Honesty • Engaged with our miracle daughter after being told I could not get pregnant.
My daughter is 5 months old. I haven't had mastitis until now, I think it happened because I skipped feedings a couple times this week when she was with a sitter. She's been sleeping through the night, should I wake her up to eat now or just pump and feed her a lot tomorrow?
