Ive been readin up on letro, ive read that some have begun letro one week befor first pin of cycle, just where it would b in the system come 1st pin. This was i believe in the case of if they were pron to gyno, such as havin it during puberbty etc. Strtin letro out at .25mg, as a precaution then bumpin up if needed. Has anyone else read or done this?? But then what about the sides of letro alone??
