Last Monday, the 16th, my boyfriend and I had sex and the condom came off. We didn't notice until after he already ejaculated inside me. We took Plan B/One-Step three hours after the incident, and began to have what I thought was side effects of the pill (nausea, abdominal pain, dizziness, and exhaustion). It has been a week since I took the pill and I have been having a mixture of a thick brown discharge and a milky white discharge switching on and off. I thought that these would be good (that my body is cleansing itself), but I am still tired and dizzy most of the time. My period isn't supposed to start until the 5th of October and I was wondering if there was a chance I could be pregnant, and how soon you would recommend taking a pregnancy test?
