Bleeding while pregnant

Mika • 28 years young TTC our rainbow baby!! Can`t wait to receive the blessing from God.
My menstrual is 5 days every 28 days like clockwork, I have been TTC and this month my AF decides to come a day early and stops after only 3 days. I have been having pregnant symptoms like; 
1. Fatigue
2. Nausea
3. Tender Breast 
4. Bloating 
5. Back pain 
Has anyone else went through this??
