Hi,
Welcome to ehealthforum,
Missing 2 or more than 2 active pills or taking them late by more than 2-3 hours on 2 or more than 2 occasions will not give you the effective protection. You are also not protected during switchover of pills (and are recommended to use additional protection). Wait and watch for your periods/withdrawal bleeding. Look out for development of any other new symptoms if pregnancy is suspected. If periods do not start within 10 days of expected period dates, or if you get abnormal periods, or if you suspect chances of pregnancy, consider visiting your doctor/gynecologist at the earliest for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Stop the hormonal contraceptive use if pregnancy is suspected, or if pregnancy gets confirmed.
Take care.
