Has anyone gone through this and had bfp??

So AF arrived May 15-16 (spotting then full speed ahead) and it was a normal amount and normal length. 2 weeks after, I start spotting anywhere from brown to pink to red to pink to brown for a whole week! AF was due to arrive this month on the 16-17th and nothing. I've taken a bunch of tests and have gotten possible vvvvvvvvf positive but not enough to get my hopes up. I took a test this morning when I got up and bfn. Not sure if it's bc I had a large water before bed. I've had weird symptoms - back pain, tingly sore breasts, crying at EVERYTHING, food Tastes weird or metal taste, crazy sex dreams, and small amount of creamy cm. What is going on?!?
