Hi there,
There may be breakthrough or intracyclic bleeding and spotting especially during the first three months of use. If bleeding persists or occurs after previously regular cycles, you should get checked for causes such as pregnancy or malignancy. If pregnancy and pathology have been excluded, bleeding irregularities may resolve over time or you may need an alternative method of contraception. Do keep us posted.
Take care and best regards!
YES! I was actually on lo loestrin 24 when I conceived.. i did miss a pill here and there however they said i was still protected i have always been extremely fertile but you should have nothing to worry about! However, most doctors do reccomend waiting at least one cycle after stopping bc to start ttc :) Good Luck
