So I'm always very regular and feel like I know my body pretty well. I always know when I ovulate because I get cramps for like 1 hr for one day. And I already felt those cramps about a week ago. I'm 5 days away from my period and really bad cramps just started about 2 hrs ago. And havnt stopped. I know my period could just be coming early for some reason but it would be rare for me. But I'm having no red discharge. I am having some light clear discharge. Any ideas what these cramps could mean?
