So how big will she be in a month or so?

Well, if she continues in her current growth chart stats, she might be as much as 26" in length and weigh 18 pounds. I'm figuring her weight probably won't be quite that high as I'm sure she was weighed with lots of clothes on. Which means I should be able to use all these 6-9 month clothes I have for her!! Whew, at least I didn't spend all that money for nothing!
