Hi...i have been suffering from irregular periods since last 3 months & also found bratholin cyst right here in labia majora on my right side since that day. During 1st month with bratholin cyst there were no blood in my periods except falthy brown fluid was coming out but no blood. Then in 2nd month i had normal periods but in 2nd week i had again but that time there was no bleeding except little brownish fluid was coming. Now this is 3rd month is going to end & 2 weeks before bratholin cyst had drained out itself though i took some antiseptics and antibiotics for cyst. This month i had periods with the difference of 3 days as before, but not its been 2 weeks there is no excessive bleeding & slight leakage of brown fluid sometines with little blood is continue.. i have not consult any doctor because m afraid of that might be m suffering from PCOS as i have read on google about it kindly solve my problem what should i ll hv to do & do tell me that bratholin cysts occur due to PCOS or it may another reason as well..i was confused because i had cyst and from the first day of cyst i have been suffering from severe irregular periods thanku.
