If I conceieved Feb 11-16 when will I start showing signs? When can I take a pregnancy test? Help! I am so excited but very scared too, this is a big year for me my boyfriend and I are getting married this summer, and now maybe a child.

This is my first pregnancy, and I am so worried. I am getting very excited, but this little place in the back of my mind is telling me not to get too excited until after I go to the doctor. Could their be a chance of it being wrong? If I calculated correctly I would be approx. 5 weeks.Thanks.
