I had unprotected sex with my boyfriend about 4 days before my expected period last month. I took the morning after pill the very next morning. My period came very late and lasted about 3 days. I've been feeling very nauseous every time i eat. Smells are also making me nauseous. I've also been feeling dizzy a lot. I took a test yesterday, which came up negative, and my period came last night. My period started very light and is also a redish brown color. I also have a "gut feeling" about being pregnant. I also had a dream i had a little boy about one year old. Could it be possible I'm pregnant?
