Menstruations nach Absetzen der Antibabypille – Beratung

In January 2022 I stopped taking the contraceptive pill after 17 years. Since then ive fallen into a pattern of having weird periods that appear to last two weeks. For a week I will have this odd spotting and then a normal period will happen for a week. Has anyone else had this? How long has it taken for anyone else's periods to return to normal? Thanks
