Hello, I would be happy to help you with your question.
I can find no information on this exposure and any risk to your fetus. Certainly there is a much greater risk to a pregnancy
than any exposure you are getting with regard to your job. Also, the heart murmur
needs to be fully evaluated with an ultrasound
of your heart, expecially in light of your recent symptoms.
I hope that this helps. If you have more questions, please click on "ASK ME A QUESTION" link above to directly ask me a question!
