Hello, this is my 3rd pregnancy and everything seemed to be going okay until around 17 weeks along (I'm now 21 weeks) when I started having episodes of feeling faint and weak which caused me to sit down right away in fear of fainting. It is so frustrating I can't drive anymore and I no longer work because I feel horrible most of the day. I had an episode while shopping a week ago when I started feeling really hot and my heart started racing and I had to sit down cause I felt weak...it really freaked me out and I started shaking uncontrollably. It was so embarrassing! ! I went to my OB 2 days later and explained the way I have been feeling and he said my blood work looked good and checked my thyroid which also came back normal. Since then I have seen a cardiologist who thinks I have svt but i still have to do a couple of tests to confirm. Has anyone else experienced similar symptoms during pregnancy and how did everything turn out after the baby was born?
