Normal pregnancy digestive issues or preclampsia?

So my stomach has been feeling weird. I chalked it up to constipation...but I have been able to go. I have had strange bouts of indigestion and heartburn....but it's short lived and comes in waves. Then on Thursday I had this flipping sensation high in my chest (like it was my heart pounding just once in a while) and it would feel weird all the way to my diaphragm where I would feel flipping as well. It eventually went away that night but now its back. I also feel bloating/pressure and like I can't get a good breath....which makes me anxious and as you can imagine makes the breathing worse. I googled (I know it's bad) and I read this could be symptoms of preclampsia. I will call the doctor in the morning but it just has me anxious.
