Advice please! Someone, anyone give me some inputadies!!!

So in pretty sure I successfully ovulated on the 17th & currently I am 5dpo & when I woke up this morning (if tmi sorry) I had a small amount of a lotion colored discharge on my undies & btw I don't believe I've ever had that before so it kinda made me go "wtf" & for some reason very very very light cramping they're not even strong enough to take medicine. My lower belly right now feels kinda tight. Could this mean possible pregnancy? & if so when should I take a test? Or should I wait?
