I need an opinion please

Let me start off by saying AF is due in 2 days. Since I woke up yesterday my stomach has been feeling kind of fluttery, like how you get butterflies in your stomach. Now today I still have the same feeling except now when I do any task around the house I and then I sit down I feel like I was doing it for hours and my chest is starting to feel fluttery. My body just feels tired like I did a lot. Physically my body has been feeling so tired but mentally I'm ok. Could this be a symptom of pregnancy ? What's going on with me
