Hi! That is frustrating, I don't do that for that long but usually about 4-5 days before. It is just old blood though. I am going to ask my dr because I feel like if it is that early then the egg doesn't even get a chance!
I am 10dpo and started spotting yesterday and am pretty sure I am getting af tomorrow. That is too early! Plus I am on clomid so it shouldn't do that I wouldn't think.
Good luck to you though!
