Heart racing...

Jessica • My rainbow baby was born on 7/25! 1 MC in May of 2014. PCOS sufferer, conceived without medication, I used plexus!! :)
Does anyone else start to feel their heart race at times when it shouldn't be? I can just be laying down going to sleep, and my heart starts to race like I just worked out or something. It's kind of scary. Google says its normal, but I'm going to talk to my doctor about it this week.
