I took 4 nordette pills last Aug 21 then another 4 pills exactly 12hrs after on Aug 22. A few hours ago I noticed brownish vaginal discharge (withdrawal bleeding?). Then I had unprotected sex where my guy ejaculated on top of my pubis after he pulled out. I wiped myself with facial tissue then baby wipes. I am not sure if his ejaculate came near my genitals. Should I take another set of nordette pills? I am not usually OCPs on a regular basis.
