DOUBLE PERIOD! What does it mean?

Hanna

Hello! I just received my regular period at the beginning of April that lasted 6 days. 5 days later, I revived a second period and I'm on day 3 now. It is very rare for me to go through this, what could it mean? What is my body telling me? I am experiencing unusual body & face acne, mood swings, cramping, and weight gain. Please help me! Comment advice!!
