Could I have a short period and still be pregnant

Melissa

So last month I had a really short period like 3 days. I have felt awful for a few weeks. Lightheaded, dizzy and exhausted. My stomach has been off and my appetite is either totally gone or completely ravenous. I’m supposed to be entering my next fertile week. I feel awful and am not really showing any signs of ovulation. 🤔

Am I just over thinking or is this possible?
