Confused

Last AF was 3/9/16 and I was due for AF yesterday.. I'm now 1 day late.. Here's what's going on.. Sorry for tmi in advance! Usually after ovulation my breast get really sore which is normal for me before AF shows.. This cycle I've been having cramps off and on nothing major.. Mind you I NEVER cramp before AF only during.. My breast now do not hurt I have been having watery discharge and I'm am 12 dpo today and got a negative hpt. Anyone else every have this and ended up being pregnant?
