PVCs in general and during pregnancy

So I’ve been having PVCs and I’m curious to know if anyone else experiences this? I have frequent palpitations, I think it’s from anxiety/panic attacks, I can also be hypochondriac sometimes. I was having them pretty much all day yesterday and ended up going to the ER to see what’s going on. My potassium was low so I’m pretty sure that’s why I was having so much yesterday. I am just looking for advice and what your experiences are. I am TTC and now that I know I’m having PVCs I’m paranoid that this will cause problems with my heart with the extra stress of carrying and delivering a baby. I am seeing my doctor to follow up, as far as I know PVCs usually aren’t caused by heart problems, but in some cases they can be. So what’s your thoughts?
