Hi doc. I am sexually active person. The first day of my last menstrual period was on 1/27/14 and i usually have a 28-31 days cycle. I have a regular menstruation and usually lasted for 5-7 days. I had an unprotected sex last 2/24/14 using withdrawal method but my partner was pretty sure he did not ejaculated inside. I took nordette after 5 hrs... I took 4 pills right away and took 4 pills after 12 hrs. It s 4th day after taking nordette as an ecp and now I m still waiting for a withdrawal bleeding. I don t have any side effects after i took the second dose except for mild cramping in my lower abdominal region. This is my first time to take nordette and I just wanna ask if nordette was still effective without withdrawal bleeding. How will taking nordette affect my period? Is there a possibility that I might be pregnant? tnx doctors
