a lot of it. unprotected sex yes, had sex during my period the last day of it then i spotted yesterday and no more spotting today what could this be? also i have been wondering during my period and while i was having spotting it felt like my uterus or my stomach was stretching i don't know what it could be but it felt like it was growing, and since my last ovulation before this period my breasts have been growing A LOT and i still feel them, when they kind of ache. it's still going on. could i be preg or just growing? 17 years old.
