What is going on?

I had my normal pms symptoms but my period isnt showing up. My cervix is medium high and firm. I was sick for a good week this past month, but i didnt take any medication. Also I believe I ovulated way later due to that (cramping in left ovary on cd 22-23). I havent had unprotected sex around ovulation time (nor when it usually is, cd 13-14, nor on cd 22-23). I feel that "heavy" feeling in my uterus before I get my period, and every now and then I feel like its going to start. Not sure what is going on.

Any ideas? Could it be a bit late because I ovulated late? Not sure. Any comment will help. :)
