Hi,
Welcome to ehealthforum,
If you have missed only 1 active pill, but have followed the missed-pill-protocol, you should remain protected. Continue to take the pills at scheduled time daily. Avoid missing any further pills. Wait and watch for your periods. 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. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. Stop the use of hormonal contraceptive if pregnancy is suspected, or if pregnancy gets confirmed.
Take care.
