Hi,
Welcome to ehealthforum,
The option suggested by your treating doctor can help you postpone your periods (you should use additional protection if having intercourse). The recent symptoms that you describe (sore & plump nipples, changed appetite, dizziness, increased vaginal discharge, changes in acne, altered sensitivity to smell) could suggest pregnancy possibility (you are not protected if you miss taking 2 or more than 2 active pills and have been sexually active without additional protection). Visit your doctor/gynecologist and discuss your recent symptoms. If pregnancy is suspected, or if you miss your periods, or if you have abnormal periods, 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. If pregnancy is suspected, or if pregnancy gets confirmed, stop the hormonal birth control use.
Take care.
