Opinions please

So I’m only a couple days late on my period so it could be nothing. It could be stress, whatever. But I haven’t had many symptoms like I normally do. My back is hurting and my boobs hurt but no cramps or anything and I have a white, almost milky looking discharge. I know people will say take a test if I’m worried or wait a few days but what are your opinions while I’m waiting until morning to test?
