Could Sore Nipples, Vaginal Discharge And Nausea Be PMS?

I had my period this month january 2011 was normal don't quite remember though anyway couple days after my period i had raw sex. Its been two weeks now i'm cramping bloated, have light headaches, eating alot an not to, have insomnia but tired more to. i feel hot, be moody, sore nipples body aches, vaginal discharge whitish color an slippery. feels like i'm on my menstrual cycle an no bleeding, an i feel nauseated. can it be just pms or what???
