Still positive

I think I explained in an earlier post that due to the HCG trigger shot I got last Monday, I would have positive HPTs (home preg. tests) for a while. Last month, I tested at 6dpo and it was negative. This month, I ordered 25 HPTs online (cheap) and started testing daily at 3dpo. It has been positive every day so far, but it's getting fainter. It should go away completely, then hopefully come back around 12dpo. I've heard of women getting a positive at 8 or 9dpo, but I won't get upset until I get to 12dpo and it's still negative. Another week of testing and I should know something!
