My period?
why do my periods come EVERY three weeks?
when i started (at 11) i use to carry my period every month(ish) afterwards stopped for about partially a year wen i was 12 and a partly then when i started again (about 13) getting my spell every 3 months, i didnt go to doctors or anything motivation i didnt think it be important. anyways. very soon when i get my length it lasts 3 days and ALWAYS a week nearer than normal. why?
Answers: Well if it is ALWAYS a week in advance than "normal" I am thinking that really may be YOUR "normal". For some women it is completely normal for them to enjoy totally random period.
periods usually come every 21-28 days. 3 days is mundane and getting them early is majority too. Its normal to hold an early cycle. It happen to lots of girls and not to mention that younger girls are more prone to having unexpected periods.
