It is a very important stage of pregnancy both to the mother and the developing embryo, due to so many changes occurring in the body of the mother and various formations going on in the fetus.

These problems include:
*Nausea and vomiting
*Difficulty with dating the age of pregnancy
*Dislike or likeness for certain food
*Breast pain or tenderness
*Bleeding from the vagina
