Panic Attacks

I’m early in the first trimester and so far my only symptoms have been sore breasts and fatigue. With my first born I was lucky enough to not suffer from any... my body enjoys pregnancy. In the past year I’ve suffered from anxiety, however I felt like I got a grip on it and thankfully not had any issues for two months. That was until last night. I woke in the middle of the night feeling slightly nauseas, I went to the toilet where I then had a full blown panic attack... rapid heart, hard to breathe, sweating and chills. Thankfully it ended after about five minutes but I had no trigger for it. Has this happened to anyone? I’m hoping this was a one off, would hate to have these start up again without any trigger!
