Not sure if i should take a test

Had sex around 2 weeks ago and again about 2 days ago. I normally take prenatal pills due to my low iron. I'm also on the birth control pills but i stopped taking them a month ago and tried starting them around a week ago and an hour after taking the pill i had very bad cramps. I was supposed to start my period about two days ago and clearly i haven't started it. I am also getting white discharge. I'm not sure if i should just take a test or wait a bit longer due to the fact that i really don't have any symptoms.
