'POTS' in pregnancy?!

Hello I was just wondering if anyone else had been threw what I'm experiencing at the moment. I've been going dizzy and feeling palpitations when standing for the past couple of weeks, I just put it down to general pregnancy symptoms and maybe not drinking enough. I went to see my dr on monday who sent me straight to the hospital where I've been ever since, Im having various tests and ECG's and they think it's a condition called 'pots' postural tachycardia syndrome. My heart rate increases from 80-90 to 130-144 immediately when standing. Just wondered if anyone else has been diagnosed with this 😔 just praying it doesn't affect/harm baby.
