Peeing all over the house is not normal, take her in and presumably your current vet is competent enough to check for a UTI. Ulrasounds can confirm if a pregnancy exists at about 3 wks old.

As a novice breeder it is unlikely that you would be able to truly ascertain by palpation and visually prior to 5 wks old. It is also possible that this could be a flase pregnancy.

I do think you should consult if you can with a reproduction specialist, baring that get a vet who themselves are experienced with breeding.

And folks will post on here what they feel/believe etc, opinions are well just opinions, and the moderators would ultimately step in, if a response goes contrary to YT posting rules, and quite frankly not the OP's rules....
