No you literally cannot get her pregnant from your penius touching her vagina. It doesn't work that way.

If the condoms are used perfectly then it's very unlikely to have gotten her pregnant.

Women's bodies aren't clockwork; sometimes we ovulate later in our cycles which causes our period to come later.

A test is accurate two weeks after sex and definitive after 3, so if it's been 14 days then she can test and trust it to be accurate.
