Healthy food makes me sick :(

Rachael • 25 years old, first time pregnancy! I'm due April 10th 2016. Pregnant by bf of 1 year.
Ugh I've been trying so hard to eat healthy during this pregnancy but it keeps making me sick!  My iron and calcium are low, I'm anemic and total protein is down but every time i eat fresh fruits and vegetables and grilled meat I either puke or get terrible heartburn or both :/ and the supplements make me throw up immediately.  Gahh I just keep telling myself.. Only 3 weeks left!!  Anyone else super ready to have the baby?
