When should I test?

Paula

I'm new to TTC #3

I've never had any type of birth control until the july 31 I took the pill for a week so I got my period July27 thru July 31 then in Aug. I got my period again on Aug 10-12, and I stopped taking it because we decided we want a baby. So now My question is when should I test? If I have not gotten my period yet?
