Still Confused /:

I've been cramping recently, so I took an opk yesterday, & it came back positive. I'm on CD23 today, & I'm still experiencing cramps & sore breasts. This usually happens right before AF comes. Has anyone had this issue? It's as if I ovulate so late that I don't have a chance for BDing. Tell me your stories please, ladies! Been TTC for 10 months now, this is so upsetting & frustrating. :(
