i went on the pill as my doctor wanted toregulate me as my periods stopped due to an eating disorder. im not anorexically thin, though i am considered underweight. however, yesterday i got my period back. but is this a 'fake' period as my doctor called it? i understand that i wont produce an egg or whatever, but does that mean if i come off the pill, that my periods will stop again? even if being on the pill and having fake periods, will this effect my fertitlity as it means that i do actulaly still have ammenhoreah? (speling>!) so i wont be able to get pregnant later on in life? or does going on the pill lessen that risk? im so confused.
