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.

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
