HI, Am I right in thinking this is an injection. My younger sister was on injections only for six months. She is 19. Her period did not return for atleast 6 months, from the time it was expected to. I still do not know if thing are back to normal.I am old enough to be her Mother(late baby). I live in USA and she is in the UK, so It is not the type of thing you just bring up in the converstion.
This might relate to my sister and not to the injection, as I know some people react in the same way to the more conventional pill.
