Even before a woman misses her period she might have some early signs and symptoms of pregnancy which begin in the first few weeks after conception
. These symptoms may/may not be seen in few women. The first signs
are fatigue, nausea, frequent urination, and breast tenderness which may be seen before a missed period .The cause is rising hormones levels in early pregnancy. Wait for your periods. If you miss them take up pregnancy test again.
Good luck and take care!
