also im wondering if what im feeding my rats is right im feeding them the oxbow baby rat blocks (not sure the actual name) also ratgirl44's seed mix she posted on youtube and then fruits and veggies every day. is that good or should i change some stuff?
I would recommend just buying the Oxbow Regal Rat from now on, there's really no need to ever use the baby formula and the adult one is healthier. C:

guess if you are following ratgirl44's suggestion of one tablespoon of that seed mix per rat per day it's okay. Honestly it is "junk food" and I wouldn't give it everyday (although I might give some cereal, etc when I am working on trust and training), especially when you already have a nice quality lab block. Fruits and veggies everyday is good, I think the rule of thumb is about 1/4 cup per rat per day.
As for knowing if she's pregnant:
No one here will be able to tell you a definite yes or no as of this stage. The only way we can say no for sure is if she has undoubtedly not been with a male even for ten seconds in the past 28 days or so.
With her weight, you only have a baseline to go off of right now. The weight watch will take time, you observe how much she gains over multiple days. You will be looking for a steady increase, in large numbers, around 8-12 grams a day I believe (someone correct me if I am wrong) but even that may be a hard way to tell, as she is so young.
Gestation is typically 21 days... You have had her for 5.
Oh that reminds me, has she gone into heat?
Unaltered females who are not pregnant go into heat roughly every 5 days. They get really hyper and their ears might twitch. There are some videos on YouTube that show it, like this one:
