dreams, 4 positive tests, 5th test negative.

So for a few weeks my breasts were super sensitive to the touch, and I normally dream everyday and remember my dreams. but for these last few weeks I was having weird dreams and remembering very little in the morning. I was late a like 5 days so I took a 2 tests... faint line. but it was a positive. I couldn't believe it so I took another 2 tests the next day also positive but faint lines. I decided to wait again to take another test figured they would get stronger but instead I got a negative and then cramping started and my period started. I bled for 3 days straight them one day it stopped and then I had more bleeding. My breasts are no longer sore and the weird dreams have stopped. anyone have any input on this?
