To be or not to be Pregnant?

Lais
When should I take a test? I never have my period (talking years here ladies!) I usually spot every three months but I spotted in the beginning of January and then last month I had my period (cramps and all!) from Jan. 30-Feb. 3rd.  I've been praying that I'm finally regular so that means I'm due for my period Mar. 30...right? 
So I guess I'm just wondering when I should take a test. I don't want to be disappointed (again!)
Thanks I advance ladies!
