Well first of all congratulatins on a new baby on the way
Many people with anxiety have stomach upsets and your also pregnant so either may be your culprit.
Did your stools have any bright red in them or were they reddish in color. Did you eat anything red, jello, cherries, red in frosting or food coloring red in something you ate?
Many people are home bound from their anxiety, others have spells where they can't go out. Again your pregnant and for the first 3 months you may feel tired with less energy.
If you continue to have the stomch problem and red colored stools you should consult your physician. I do understand your loss of taking you usual med causing you anxiety too.
I wish you a healthy pregnancy and keep posting, we are here for you.
