First trimester

Gail • I currently have two kids a boy and a girl I love so much but now that they are getting big I want another baby!
All I ever want to do since I found out I was pregnant is sleep.. I sleep so much to the point where I don't want to get up for work and go to night class In the afternoon. I'm already taking vitamins to help me make it throughout the day. Is there something I can take or do for more energy because I know that I can't take any over the counter medicine unless it's prescribed by my dr
