So this past month AF came early (UH-gain) and I was pretty sure what it was, but when I told my friend she said, "Oh, if it's early, it could be implantation bleeding!" I was pretty sure it wasn't, but after she said that I was all paranoid about using a tampon. I have very sensitive skin, and as a result, pads and me do not mix (not sure exactly what it is about them), so I ended up wearing the "period" underwear, then bike shorts, then pants to work (yes, it was gross). I've decided to suck it up and get some pads just in case, but I was wondering: if I had implantation bleeding, and thought it was AF starting (like starting right as I noticed the bleeding), and used a tampon, how bad would that be? Should I just not use tampons for a while, or start with a pad, then switch to tampons when it becomes clear that AF has come? I'm hoping this question is irrelevant, of course, but I really dislike dealing with those rashes that I get from the pads, but I'll deal with it if it's a big enough risk. Thoughts?
