So sunday

I was supposed to start my period sunday but nothing. It is now tuesday night and theres still no sign of af. Today ive had all kinds of wet feelings down there but no blood just really thick white discharge. Could i be pregnant? Oh and my boobs always hurt the entire week before my period but my boobs didnt start hurting until saturday night but now they barely hurt. I want a baby so bad oh and earlier today the discharge that was thick and white had snot lookong parts to it
