it would be highly unlikely that pregnancy could occur from the scenerio that you described. there are many things that cause a delay in the menses including stress. because you both are engaging in intimate sexual activity it may only be a matter of time before you both decide to go the rest of the way and have vaginal sex. i would strongly suggest that you use condoms and that your girlfriend be on another form of effective birth control.
can oral sex combined with kissing possibly result in pregnancy? . recently (a few weeks ago) my girlfriend performed oral sex on me and swallowed. we made out (the taste of semen was present in her mouth) and then i performed oral sex on her without thinking that i could have sperm present in my mouth. her period is now somewhat late in coming so we are both worried that she might have gotten pregnant. i know that there is at least a small chance of it but could she have feasibly gotten pregnant from this scenario?
