Missed period of May I took a HPT was negative the following month I spotted two weeks early it's brown then red but it's not a lot and slight cramps?

Ovulating? Besides pregnancy one of the more common reasons women skip periods or have irregular bleeding is that they are not ovulating. There are many reasons why this happens. If it is persistent, you might want to see an Ob/Gyn for some testing to find out why. Best wishes!
