What Cause Milky White Discharge After An Unprotected Sex?

My boyfriend and I had unprotected sex the first day of my next birth control pill pack, I missed the pill that night (as I take it before bed every night) because I wasn t able to get to the pharmacy before it closed. This was exactly a week ago today. My birth control instructs me to take two pills in one day the day after I ve missed one. I ve done this a couple times before and each time it causes vomiting and nausea, this time around was no different. Monday morning I woke up around 4:30 and was sick. The nausea went away by 9am and I was able to keep food down for the rest of the day. However, later that day I noticed I had a milky white discharge, I didn t give it much thought as I am often a victim of yeast infections, I get them roughly once a month. The milky fluid was exactly like any other yeast infection I ve ever had. I have also experienced mood swings this past week accompanied by a constant hunger, I just eat all the time. I ve also just now developed a soreness/tightness in my lower abdomen just above my pubic bone and up in my groin area just under my hips. It is most painful when I engage my tranverse abdominal muscles, as if I ve worked them out. I m absolutely terrified that I am pregnant because I cannot afford a child right now but I know that some of these are considered signs of early pregnancy. Please any expert advice that you can give me would be much appreciated.
