worries part 1

I named this "part 1" because there will be THOUSANDS of worries.
Corey, my yoga teacher and awesome bud says all you have to worry about is loving your baby; everything else is easy.

Agreed but.....remember the stress machine part? So current and past pregs: how do you deal with the following fears:

Losing the baby (there. i said it)
Working out too hard
Not working out enough
Not getting enough of a certain vitamin and how would I know?
Is there a reason I have no morning sickness?
I thought you peed like a million times...um no. Same as always.
Is 140 really max bpm? That's like BREATHING heart rate.
When walking my 80lb son Ranger, how much pulling is too much?
If I really didn't eat fish before (unless it was served fried with fries), can I start now to include more good fats, considering everyone shudders at the thought of fish during pregnancy?


Know that I come to this as a die hard runner, yoga teacher/student and clutzy, clumsy, dog wrestling junk food lover. oy.
