Wait, 5 months or 5 weeks?
Anyways, pee pads are incredibly counterproductive.
Keep her crate close to the door- as soon as she comes out of the crate, she goes outside until she potties- however long it takes. When you bring her back inside, she still needs to go out every 20 mins or so.
As for the crying, many puppies do it...especially that young. My pup screamed for quite a while. Initially, you have to just let them cry it out- no attention, no scolding, no nothing. Covering the crate with towels so they can't see out often helps.
