All answers and advice is greatly appreciated! Do any of you have POTS, tachycardia, and/or low blood pressure? I am not asking to take place of a medical professional’s advice. I am just asking if any of you have experienced this and turned out to have a healthy pregnancy and delivery while taking these medications. I know there is not much research but I was told that some beta blockers cross the placenta. I tried to stay off the medication but I can’t due to passing out and severe problems.
