the first step is to treat her like she was pregnant , a good quality puppy kibble is the best you can do for her right now if you are going to see this pregnancy to the end.
right now she does not need any more than that since is VERY early. at about 32 days you can take her to the vet and have him or her palpate her abdomen to verify that indeed she is pregnant, my vet is the best at doing that she is so good she had even told me how many babies to expect..start looking in your area to see if you can find a mentor to help you thru the whelping. and Keep reading and reading and asking questions.
best of luck, remember the life of your girl is in your hands now, the more you know and the more you learn the easier is going to be for both of you at whelping time..
also another solution could be an emergency spay.
hugs,
Carmen
