First off: Congratulations on your little bundle!
Second: you're going to start receiving a lot of unsolicited advice, even from people yen know. It's weird, but it happens, frequently.
Listen to them, say thank you, and then decide what works you.
Don't let anyone pressure you into doing anything you're uncomfortable with. Oh, and sleep when you're tired. Soon enough, you won't be able to. =3
Congrats on your first pregnancy. I am 12 weeks due Sep.27, 2016, this is my second child...hoping for a boy this time. Anyways all your symptoms are normal for your first trimester. I had the same ones with my first and again with this one.
