missed a growth spurt?

J
My LO decided to eat 32 oz of milk while I was at work yesterday. I work 12 hour shifts which means I'm actually away from him for about 14 hours when I work. I think he might have had a growth spurt because my husband said he just cried and fussed and ate all day long. I'm worried that if I missed his growth spurt, I also missed the chance for my body to produce more milk for him. I'm pumping at work but it's not the same as my baby. I bring him about 20-22 oz from work. I already have anxiety and guilt about having to work full time, and feeling like we're out of sync is really upsetting me.
