Hello, I would be happy to help you with your question.
Iron pills are associated with constipation
. Some of the upper abdominal discomfort
could be related to this constipation, even felt in the location you are describing. But the fact that you are having other odd symptoms, and given the relative high location of this pain AND given that you are 35 weeks along, a call to your doctor to come in to have your blood pressure checked would be a good idea.
I hope that this helps. If you have more questions, please click on the link above to directly ask me a question!
