Yesterday was cd13. I had some cramping but when I took my opk at 7pm, it was negative. We baby danced last night just in case that was ovulation. I am really hoping it wasn't because I really want to get a positive opk to know! 
The cramping started for about 10 minutes then went away and then last night my whole body hurt. Could that just be Clomid symptoms or ovulation?
