YUP....I spotted light brown for a couple of days with pg#2. This was before I even knew I was pg so it was early. I spotted bright red at about week 8 with both my pregnancies! .....I have 2 healthy boys....so I wish you HUGE luck!
I definately heard NOT to use a Keeper with an IUD...but never heard the tampon one. I've had my copper T IUD for about 3 years and used tampons each month. So far I have not had any problems. I do know that my IUD strings are cut high in my vagina. Maybe you can request that.
