question: Hello doctor,I had been put on Primolut N for 15 days for PCOD. I started the pills on last month and finished in 15 days. On the seventh day, I had sex with my husband. I got my period on the 21st day and had been asked to begin Diane 35 for 21 days on the fifth day of the cycle. I began taking Diane 35 on 25th of last month and the pack finished on 15th of next month. Today is the last day of the pill-free week but there is no bleeding yet. I had taken an emergency pill within an hour after the intercourse. There has been no sex after the last cycle. Should I worry about an unwanted pregnancy? Please help.
