Need to know - am I Pregnant ??

I was ovulating November 1st - 5th. My fiancee and I had unprotected sex all that week. My expected period wasnt due until November 19th. I started having this light/meduim flow light pink and some clear/whittish discharge that lasted for 2 days then stopped. I had cramps and lower back pain. All ways tired and more trips to the restroom. Now it December 6th My boobs feel heavey no soreness. I can see blue veins in my boobs here and there. Its hard for me to breath at some points of the day. HTP test come back as neg. Any advice please!!!!
