There is a 3 week growth spurt but I swear that my DD went through it at 2 weeks. I don't know how long that one lasted (can't remember honestly). Her 6 week growth spurt lasted 2 weeks! I'm gearing up for her 3 month growth spurt so I'm ready!
There's supposed to be one around 7-10 days, which is an average, so your LO is probably doing that. The next one is roughly 3 weeks, then 6 weeks, then 3 months. She may be crying and eating all day, but eventually she will be full and very tired. Once my DD finally slept, she was out like a light!
