 [ Symptoms ] 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 [ Disease ] 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
