I need advice


My husband and I are ttc for three months now off BC, I was supposed to start my period Wednesday, it is now Friday. My period last month was weird, only last two days and the second day was very light. Tonight I’m having slight cramps and a very light pink discharge and a very small amount at that.

When should I test again? Or is this just a normal period starting and I’m over thinking ? I would like to add , I never spot before periods. It’s usually a flood when it comes. Thanks in advance.
