I have an OSOM in my purse and I'm going to test this afternoon when I get to a "true" 2 days past 5 day transfer.  It should be negative, but heck-- I have 25 tests and I ain't afraid to use them.

Oh, here's a fun new numbers game.  Working backwards from my beta last time.

Assuming a 24 hour doubling time first:

9dp 300
8dp 150
7dp 75 
6dp 38 
5dp 19 
4dp 10
3dp 5
2dp 2

Or how about by betas from Leo's pregnancy, when there were twins:

10dp 1400
9dp 700
8dp 350
7dp 175
6dp 85
5dp 42
4dp 21
3dp 10
2dp 5

So yeah.  Today's test will be negative.  Should I even bother?

Answer: yes.  In the name of science!  I need a baseline.
