Am i pregnant?

Katrina
I have a bad cycle ranging from 32 to 45 and now it's day 47. I have sore boobs and had 6 negatives taken days apart. Still no period except symptoms like sore breasts and some bruising. My cm is dry but when I wash thoroughly, there are creamy cm washed away. 2 days ago there was a small brown cm washed away. I'm getting frustrated. My bf and I have been doing withdrawal for 5 years and I never got pregnant. What's going on? I need help really.
