I know this might be a dumb question but I've been having paranoid thoughts about it.. this might be long but I really need some insights about so I'll start of with my last intercourse which was on December.. i had my period on december, skipped january, had again on february, then experienced long cramping period so I decided to go to an ob gyne/sonologist and had my ultrasound last March 17th.. the sonologist found a corpus luteum and that I'm on secretory phase endometrium that time- meaning I was done ovulating and wasn't pregnant) my boyfriend fingered me on march 20th (added this just for the details) then had my period on march 31st to april 4th (I just started tracking my cycles since September and it ranges from 33-37 days with an average of 34 days.. My period also lasts for 5 days) on April 5th (CD 6), I was playing with my bf's private part and accidentally touched the sides of my vulvar region (on the pubic area side and I was wearing my underwear and napkin/pad that time) and I then rubbed myself on top of my underwear with pad until I came.. on April 6th and 7th (CD 7&8) I had brown spotting (maybe due to blood from my period)..On April 13 and 14, I fingered myself with my kinda long nails and I had brown spotting on the night of April 14th (CD 15) and I also had a cervical mucus like discharge with a brown stringy discharge on April 15th (CD 16).. Basing on my 34 days average cycle, I'm expecting my ovulation on April 19/20.. Now I wasn't sure if that discharge was due to my long fingernails, ovulation spotting, or just a random unreleased blood from my period that has been triggered by my fingering.. I'm now expecting my period on May 4..

Can sperm swim from your vulvar region into your vagina if you accidentally touched your vulvar region with your finger that might have some little to almost dry precum?
