Keeping my bean safe?!

Stephanie
I worry about my little boy so much. I'm around 15 weeks (I say that bc my dr changes it every week so I have no idea how far along I am exactly). Today I was able to see him. He was laying facing down so I was able to see his strong spine and strong heartbeat. We were able to see a little bit of his arm, hand, and leg. Dr told me to start taking Calcium with D supplements in addition to my prenatals. I just want him to be healthy and strong. Anything else I can do? Besides pray bc I do that already! Next week I do a blood test to check his spine and abdomen.
