I just ended my period
on Sunday, so I know I am not
getting it again, I haven't had sex since my last period
, so I know I am not pregnant. I am really confused, my periods are ALWAYS regular, so that does not have to do with it. I have been taking adderall here and there the past few weeks for studying purposes, so I have lost around 5-7 pounds (I have not been eating as much as normal), maybe that has something to do with it? Please let me know if anyone has any ideas.
