Hi, I'm a 23 yr Asian girl, single. Height 5'3", weight around 58 kg. My periods are 10 days late this month my date was 19th and today is 29th. Also my breast are little bit asymmetrical, I'm feeling itching in right breast for last 2-3 days and also an increase in size of right breast. I use to masturbate once a month, is this happened because of that?
