Question?????

I'm currently 22 days late ( period). I was supposed to get my period on January 8th. On January 20 & 21 I was spotting like I was about to get my period, but my period never came. Right now I'm having a little bit of pain on my right side ovary. I do not have any symptoms. I did test at the beginning of missing period and it was negative. Have anyone experienced any like this???
