Hi Sara,
Did you do a Day 3 or a blastie transfer? If Day 3, you would only be 10dpo, so it might be too early for AF? If a blastie I guess that would make you 12dpo? Is that right? Remember spotting can be implantation spotting so might be too early to worry. I really hope AF is not on the way, hang in there, this could still be the month.

I too am bumed, have been on the verge of tears all day. Will do another HPT tomorrow (14dpo) just in case but not holding any hope. DH has sent me flowers to try to cheer me up, but it is not working. Just feeling so frustrated and 'why me' and 'it's not fair'.

Like you said earlier, it is not over til the AF shows, so for you.

Hugs!
