I feel so disappointed. Last night I took a frer And I got the faintest, I mean eye squinting faint, but clearly there. Today however...nothing!!! I'm 10 dpo. Could it just be too early. I read hcg doubles every 2/3 days but wouldn't I see an equally faint line today as well? Ughhh....after trying for months I finally got my hopes up and I feel so let down now. Why would the line go away?

Please advice...
