I have been suffering irregular periods badly for a year I came on my period too much and lately I have been having one day periods with the mother off cramps, i went on an ultrasound test last year and pcos was ruled out however my doctor said she wants to do vaginal swabs? Is that a pap smear? Im a virgin so im worried because no one can find out why im suffering from irregular periods. What can vaginal swabs show for me as a virgin? Im really worried fertility wise for the future. Help please!
