Awful cramps

Jessica • From Iowa, 25 years old and trying for our first baby.
I am experiencing day 3 of terrible cramps, the first day I had light pink discharge, then red discharge, now nothing but awful cramps. I'm not supposed to get my period for another 15 days and according to glow, I just ovulated yesterday. My periods are 7-8 days and I just had mine the 16-23. Does anyone know what's going on?
