Breastfeeding and upset !

Yesterday me and baby and my boyfriend went out of town didn’t think we’d be gone to long so I didn’t bring my pump cause I was going 12 hrs without pumping before I needed too . Well yesterday about 6 hours had gone by and my boobs were huge and leaking , we still decided to stay cause my aunt was giving me her pump , we sanitized it and I didn’t end up using till almost 12 hours after I had last pumped , I pumped till when I normally do when there soft and I feel like there’s no more milk coming out and ended up with roughly 12 ounces per boob Which is pretty normal cause before i was getting about 9-10 ounces per boob . And now my boobs don’t seem to fill up even within 6 hours of not pumping . I’ve only been getting anywhere from 5-8 ounces that’s with boobs combined . Did I wait too long yesterday to pump and now my milk is starting to dry up? I wanna cry cause I really don’t wanna formula feed him .
