Cramping in early pregnancy

KJ
I'm 5 weeks 3 days and I have had cramping since ovulation. I spotted for a few days up until my period was due and have not had any since. The cramping today is pretty bad and feels a lot like period cramps. No bleeding but I'm getting a little worried that something is wrong. The pain seems to be pretty even across my lower abdomen but occasionally localizes to the right side.
