I take birth control and have never missed a period. I recently had to take a prescription, & used a backup method. It failed, and I took Plan B. I have taken all 4 sugar pills, and havent started my period. I took a pregnancy test, and it came back negative. Should I start my next pack of birth control pills on time?
Welcome to ehealthforum.
Wait for your periods to start. Sometimes it takes longer to start your periods after taking combination of hormonal pills (regular and emergency birth control). Usually you have bleeding after 5-7 days of emergency pill use. If you do not start your periods by the time you finish with your placebo pills, then visit your gynecologist for examination and tests to confirm/rule out pregnancy. Do not start on next pack unless it is confirmed that you are not pregnant.
