Need your help and opinion ladies

So I'm am very confused and have no idea what is happening, I am supposed to be ovulating today, my peak day, according to glow. I am not supposed to get my period for another 16 days, and yesterday I had awful cramps and pink discharge, I thought it could be because I'm ovulating and possibly implantation. But today I am still having severe cramps and my pink discharge has turned red- like the start of my period...but 16 days early on the day I am ovulating? I am so confused and hope someone can tell me what's going on?
