Late Period: Pregnancy Possibility & Early Symptoms - Expert Advice

Question
I'm 21 yrs old, and have no children. The first day of my last menstrual period was April 13. My period has been late for 5 days, and I'm wondering if I am pregnant or not. I had intercourse on April 28 or 29, my boyfriend didn't ejaculate inside of me (which I know isn't an efficient birth control method). So far, I didn't feel any early signs of pregnancy except that my breasts are slightly sore, but I usually get that when I have pms too. Is it too early for me to feel the symptoms? Is it possible that I'm not pregnant?

Answer
Since your last period started on April 13, you probably ovulated on April 26 and could have conceived if you had sex on April 25,26,27,or 28. The best time to take a pregnancy test is seven days after missing  your period. You are de for your period on May 10. A pregnancy test is accurate after May 17.  You can start symptoms (breast tenderness, fatigue, nausea) anytime after conception.      You may or may not be pregnnat. Take a pregnancy test and you know for sure.
