5 DPO

I'm 5 DPO, my period is due around the 20th but i had a miscarriage a month ago so I'm not sure exactly when/if it will come. We've been TTC and since ovulating, my boobs are sore, I keep cramping and also getting A LOT of EWCM. Could this mean I've conceived? I don't think this is normal for me so I'm not sure if it could be that I'm pregnant or AF is coming.
