Anxiety is getting worse?

I’m currently in week 4 of my gestational period and recently I’ve been waking up with severe breathlessness and anxiety. My mind may occasionally worry about my baby, but my physical symptoms seem to be getting worse. I struggled with anxiety when I was in university, but as I went on to work I learned to handle it better and it never felt this bad before. Has anyone experienced this? Is it the fluctuation of hormones that is causing this?
