I have guaranteed myself a BFP by registering for a charity marathon walk (26.2 miles, obviously) in September that I will not be able to do if I'm KU. By registering I am pledging to raise a minimum of $250...which will be charged to my credit card if I don't raise it...whether I walk or not.
I have guaranteed myself a BFN by starting Clomid in a cycle that would give me an April due date, perfect for me as a teacher. So, obviously that won't work out.

I think you'll have to pay but not walk. I've guanteed myself a BFP in the next couple of months because they make for due dates at the busiest time of year for me. Oh well, I promise I won't complain if it happens
