Question !!

I found pictures of NAKED women in my husband's phone . He said he never deletes pictures from his phone but it was right by my pictures i sent to him recently. He claims that he would never cheat on me & ughhhh idk .. the whole situation is messed up to think about . Idk if im being reasonable or being jealous but its bringing a lot of stress on me & i could be pregnant. Any advice ? What do you ladies think i should do ?.....
