No matter how much she eats, you always have milk in your breasts... ALWAYS. I'd buy a cheap manual pump and pump for 20 minutes before you feed her EVERY TIME you feed her, that way you will quickly start up a supply of expressed milk. After her feeding, pump again for another 10 minutes in the same container. The first few times you pump, you may get little to nothing out, but the more you pump the more you will be able to express and freeze.
Formula introduces foreign bacteria and proteins which will inflame and irritate your baby's open GI tract. It take over 2 weeks for the effects of formula to leave a baby's system.
Yes, every 2 hours sounds right... but don't worry it will not always be this way. Some days will be a lot less and during growth spurts it will be a lot more ;)

Which also contains 2 additional sites for info.
The point of these articles is to point out that, yes, it can hurt. Babies are born with "gap junctions", or spaces in between the cells in their digestive tract. Foreign proteins in formula can get into these junctions and form immune complexes, which can lead to sensitization and allergies later in life, especially to cow's milk. Colostrum coats the intestines and fills in these junctions.
Formula can't perform this function, and introduces foreign bacteria into the infant's digestive system. The "bad bacteria" in formula can also cause overgrowth of the bacteria that have colonized the infant's gut, which can lead to diarrheal illnesses and NEC, or necrotizing enterocolitis.
Why is that a problem? Have you been hearing about the "good bacteria" that formula companies are starting to add to their product, in their quest to once again be more like breastmilk? (A goal they will never attain, because breastmilk composition changes throughout the day, week, and as the baby grows to continually meet his developing needs!) A baby who is breastfed has the benefit of this good bacteria until solid foods are introduced. Getting this bacteria from formula, however, can pose a problem, because it can overcolonize and cause sickness- say if one can or bottle contains more than the amount the baby needs.
I found it interesting in the second article that after supplementation with formula, it can take 2-4 weeks for the good bacteria to recolonize the digestive tract, if the supplements are stopped. So even small amounts of supplementation can change a baby's gut in as little as 24 hours. Is this really good for babies?

The human digestive system has a layer of mucous that protects the gastrointestinal tract from microbes and other contaminants that may be present in food or liquids. In infants, this protective barrier is immature, which puts your baby at risk of infection. Antibodies in breast milk help protect your baby until his digestive mucosal lining matures and he increases his ability to produce his own antibodies, which happens around the age of six months.

The infant's protective mucosal barrier is immature at birth. As a consequence, pathogens and other macromolecules can potentially penetrate the intestinal epithelium and enter the infant's circulatory system. This can increase the infant's risk of infection as well as the development of allergies. "There are antibodies and other large immune molecules present in breast milk," says Brenna, "that can help support the baby's immune system." The main antibody providing protection in breast milk is called secretory IgA. As the infant's digestive system continues to develop, it will become much less permeable to large molecules. This coincides, however, with the baby's increasing ability to make his or her own antibodies.
