Sore Boobs

well I got a schedule with my milk and yesterday i messed it up so now I'm sore and too much milk. I've always pumped 4 to 5 oz from side and 2oz( to leave some for the next fedding) from the other at about 5 am to 7 am. My breasts are used it and then give me about 3 oz for all the other feedings for the rest of the day. Yesterday i skipped it on the morning and the girls were engourged too much milk. finally pumped at 2 pm to get release but still too much milk.
