Friday morning, I thought AF was starting as scheduled. I had bright red blood when I wiped that morning. I put a tampon in and went to work. When I removed the tampon, there was only a very small amount of brown spotting. I haven’t used a tampon since then. My panty liners have only had a few drops of brown spotting and some when I wipe. I had no “normal” period symptoms like I normally have. No cramps at all. Is this implantation bleeding? It’s now Sunday and still no BFP.
