Patient's question:
I used to have irregular periods. This month, I took the combined ethinyl estradiol tablets for the first time as instructed in the manual. I don't want my period to come a week early, and I still have four pills left. Should I continue to take the remaining four pills? Will it affect the contraceptive effect if I don't finish them?Doctor's answer:
