Lupron depot suppression heavy bleeding

Hi. I had my first lupron depot suppression shot on Dec. 13. And exactly 2 weeks later Dec. 27 I started having headache, bloating and bleeding. I know they said that spotting could occur while on the lupron suppression but I never had any spotting for the past 2 weeks until today. Also, this feels and looks like my usual period. Iam not just spotting iam having heavy period bleeding with very tiny blood clots. Is this normal? And how long will it last?
