15 DPO. Still faint lines

val

Guys I am getting these faint lines and Im on my second day of missed period. Not sure whats going on. I had a vvvvvvfl on clearblue cant even take a pic of it. Feels like AF is going to come knocking any moment but nooooo I have clear discharge everyday and cramping plus my nipples are so hard and painful if I touch them. Did anyone experienced the same?
