Went in at 11am for my beta. It's ten after 6 now and I'm still waiting for my phone call. I know it will probably be negative bcause of the HPT BFN yesterday morning... but I did a search on FF for charts with "negative HPT before positive HPT" and "late HPT+ (>15dpo)" and came up with lots of matching charts, lots of women who had gotten negatives at 13 and even 14dpo, then a positive a few days later.
If there is one thing a woman who is TTC can do well, it's hold on to hope.
How long do most women have to wait to find out the results of their beta?
