AF is due on Monday. I have had very light brown discharge Thursday and Friday and some pinkish color today. Only when I use the restroom and not all the time. I feel different. My breasts are extremely sore and feel heavy. They usually don't ache like this. I have very mild cramping but it also feels different, more twingey and pulling. The cramps even seem to run down my leg. I have taken one test today and BFN. Could I still be pregnant and this be implantation bleeding or is this just AF beginning? Anyone else experienced this? I'm hoping for my BFP and would be crushed once again if it is. Any help, advice or prior experience would really help! :) Thanks ladies!
