4 days late

Lexy

So I’m currently late on my period by 4 days and I’m still having stretchy white discharge..but I came out negative on both blood and urine tests.Idk what’s going on with my body but I’ve been having lots of backaches,acid reflux,nausea,and mood swings…my gynecologist did seem a bit worried when I saw her,she gave me the”uh oh”face as if I could be pregnant again but they tested me before my missed period and came back negative..
