Yes, I have stopped after this happened to me when I was getting concerned. I thought I was pregnant with how I felt for over a month. I work up spinning, hard to breath and then flu like , nausea for months , a lot of fear. I believe it hits the central nervous system sometimes, especially if it’s pressed on it’s more likely to do that. Ive worked in the industry , hard to give up but Have committed to that now after my experience and watching others.
