Let me make sure I am following you.
You had sex with your husband on day 13 of your cycle (ovulation time).
Now your period is not coming.
You don't need medication, you need prenatal vitamins.
If you are inside the U.S. see a pharmacist.
If you are living outside the U.S. you may have to see a doctor first.
You need to see a gynocologist Dear. If you were on your period for 13 days, you need to see a doctor. Unsafe sex?? With your husband?? That just sounds strange to me.
Before considering taking any medication, you should first take immediate steps to determine if you are pregnant or not.
Other issues may be contributing to delayed menstruation, that only a qualified doctor can detect when examining you.
If you are in an urban environment and have the means, seek out a doctor or at minimum purchase a home pregnancy test.
If you do not have the funds, surf the Internet for local health resources for women.
Most of all, try not to worry. Maybe you will get a lovely child!
