Late Period

So I’ve been using eve for the past 3 months. Last month my period came right when eve predicted it too. I’m freaking out because it’s been 5 days late. I had a really stressful month and I know stress can throw it off. I’ve never had sex but my boyfriend and I have done other things I’m worried that I forgot to wash my hands and I touched myself after pleasuring him or that he forgot to wash his hands while fingering me. Can I get pregnant from this? Help! Sorry I’m not very experienced with this stuff.
