kay .. i had sex with my boyfriend on the last day of my period and the week after that .. during the later intercourse, i cummed so much enough to make his matress really wet tho there's one blanket covering the bed itself. when i was going home that day i felt like i've been cumming fo no reason that i have to change my underwear everytime. the day after, i saw brown mucus on my underwear thought it's another period but then i know that i had it the last week. the day after ( saturday ) the later intercourse ( friday ), i've been feeling wierd down my stomach just below my belly button. and it's still happening till this day ( wednesday ) i went to the doctor and he said it might be gastreous but if there's a possibility that i am pregnant, i should take the test to make sure. to add to that, i've been feeling that i have to take a bowel more often than before and my knees are getting weaker because of the pain. also, i've been getting wet down there that i can't even explain it myself.
