No perood, brown discharge for 3 days, bfn

katie
I was due for af on Sunday July 2nd but nothing came until on monday July 3rd I got dark brown and pinkish spotting for 3 days. Very light but still lasted the 3 days. Now it has completely stopped. Since last Thursday my period has been high and closed. Sometimes really high and sometimes just normal high. It never went down that I felt. Some days it was like really hard, very very weird I've never felt that before, and then it would get really soft and sometimes it was in between. Today I took a test and it was a bfn. I thought I saw a line but it was almost obviously my eyes playing tricks on me. So idk what's going on. Anyone can help me? Thank you!
