period symptoms,bachache,stomach ache,but no bleeding?

Hi,
Welcome to ehealthforum,
Sometimes you can experience 1-2 missed periods while being on the hormonal contraceptive pills. The pills can also give you failures (especially if you are not regular with taking them at scheduled time daily). Wait and watch for your periods. If the symptoms persist, or if you suspect chances of pregnancy, or if you develop symptoms suggestive of pregnancy, you should consider visiting your gynecologist 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. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
