Started bc midcycle about 2 weeks after my period. My period came for 11 days after starting the pills, is this normal? Are the pills effective yet?

Normal. Starting pills midcycle is not recommended because the pills are out of sync with your natural cycle. This can give you irregular bleeding like you are experiencing. It may take a few months for your body and the pills to sync. In your case, the pills won't be effective until you have been on them at least 2 weeks. Best wishes!
