Early Pregnancy Signs: Nausea, Pelvic Pressure & More

Question
Hello, I am 30 yrs old and have one child. I have a 26 day cycle.  The first day of my LMP was 12/18/05, I had unprotected Sex on 12/29/05.  Would it be possible at all to have pregnancy symptons yet?  Like a little pressure in the pelvic area and nausea?  I have felt kind of nauseous on and off yesterday and today.  Thanks

Answer
The earliest symptoms of pregnancy are nausea, fatigue, and breast tenderness. If you have a 26 day cycle and your LMP was December 18, you would have ovulated on December 29 and could have conceived if you had sex on December 28,29,30, or 31. Usually, symptoms can be appreciated within a week after conception. A pregnancy test will not show a positive result until 14-21 days later. The best time to take a pregnancy test is seven days after you miss your next period. Good Luck.
