Definitely suggest looking for a job before you start showing! I was sick for the first 16 weeks and the only thing I enjoy is seeing baby girl on ultrasounds and seeing her move.
Hopefully you have friends/family to ask/help you with all your pregnancy questions. There is so much you don't think of until you get pregnant. I told my close friends and mom I was pregnant as soon as I knew. Told others when I started my second trimester
Try zofran for nausea. Your dr will write you a script for it. The next thing is the fatigue does go away...eventually. lol. As to when to tell that's a personal choice. There's no rules. It's up to when you want to. As for complications. Don't stress it. You're likely to have a "typical" pregnancy. Why kill yourself over every what if? Now, most importantly. CONGRATS!! : D
Also I throw up everything I eat! Any suggestions?
