2 weeks ago I performed oral sex on my boyfriend - but we were in a bit of a hurry so I spent around 3 minutes down there tops (embarrassing, I know!). We then kissed for a while before he convinced me to let him return the favour - this was only in a short lived burst too however and he spent more time kissing his way down haha! He didn't ejaculate until I'd got dressed and I don't recall any precum but you never can tell. I'm now a tiny bit anxious that this could have caused me to be pregnant but then again this could sound really farfetched and ridiculous (I often overthink things A LOT). My period has is nine days late and I have been experiencing some white discharge. However, my periods have always been irregular so I'm not really sure if I'm just getting stressed out and paranoid (I'm known to be a bit of a worrier)! For example my previous two periods have started May: 17th June: 13th (In the past I've expected a period on the 26th of a month and it's not arrived until like the 5th of the following month!) I've also had some mild cramps, however, these have only occured after reading up on early pregnancy symptoms so I'm not entirely sure whether this pains are triggered by psychological causes such as excessive stress (I've been tremendously stressed out this past week). Any responses will be greatly appreciated. I realise how immature this probably sounds and I'm kicking myself for being stupid enough to do this without using a condom (what with the risk of STIs and STDs). PS - I'm unable to go on the pill since manic depression runs in the family and I've had previous experiences of it triggering suicidal moods when I was taking it.
