Pretty intense cramping after workout

Evette

So I’m supposed to start my period in 2 days and I’ve recently started going to the gym. I’ve noticed that I get cramps and spotting after going to gym and doing so heavy workouts. But this time it really hurts and the bleeding is not super heavy but enough for me to want to put on a pad or something. I don’t know if I should be worried or if the exercise kicked in my period a little early . I would appreciate any advice from you ladies or maybe similar experiences?
