Going crazy!! Need advice..

 So AF didn't come last month!!! Got a big fat no! (Twice) May 30th 8 days after ovulation if AF showed up. I started spotting very light and pink in color for three days.. Wednesday I started my period.. But it's not like a normal period its lighter no cramps ... And I have the worst mood swings.. I thought the spotting was impantition bleeding .. But now I'm sure and going crazy..
