Bloody discharge??

Kathyrn

I’m pretty young and have a usually very heavy period for at least 6 days every 22-28 days I’m on cycle day 26 and today I had a lot of white/pink bloody discharge I’ve never experienced that before? I have not been sexually active(other then orally in the past 4 months) I also have been having a lot of boob soreness and stomach aches which are normal and a symptoms before I get my period but still I really don’t know what to do? Help?
