You shouldnt worry about what others think of your age btw.. im 23.. my parents were in their 40s and didnt have full custody of me.. my husbands parents were 15 and they raised him together. . Most symptoms are nausea insomnia peeing all day and heartburn and breast tenderness
You will start experiencing fatigue which is lack of energy and sleepiness ... You start feeling nausea and often accompanied by vomiting early in the pregnancy ... 1st trimester is rough but get "what to expect when your expecting" book it tells you a lot about each week and month of pregnancy
