Callling all College Athletes

Hey everybody I’m a freshmen on a d1 sports team and I’ve been noticing some weird things with my period. My period last month was 4 days early and light with very little cramps- big change for me because I have always gotten severe cramps to the point of puking. Now this period is a week early! And it’s super light and the blood is really dark and chunky? Sorry for tmi- could this be because I’m working out much harder now? Or something else?
