Kenda makes a great point - RELAX!

Listen to your baby and follow her cues.
There is no time that it is too late to start pumping, and like Kenda said even if you don't get much in the beginning your body will respond and you will be able to pump more and more. Your breasts are continually making milk, so even if the baby drinks it all, she can still get some out of your boob. Make sure when you do give her a bottle you find one that has a wide nipple on it so she has to keep her lips open while drinking, and the slowest flow nipple you can find.
Technically, you count time from the start of one feeding to the start of the next. That was frustrating for me, too, with Vivian because she would sometimes only go 1/2 hour off the boob because she nursed for so long
You're doing just fine! Pump whenever you have some free time, but you might have to wait a few days until this growth spurt is over just to get that time

Keep doing what you're doing and your baby will grow, grow, grow
