Hi Bees! I'm looking for some excuses to add to my arsenal as to why I can't do certain things because we're going to start TTC next month (and we're not telling many people about).

Example 1: A friend just sent us a link to a trip they want to book for February to Africa and want us to come along. We've traveled with them a lot, usually in February, so I'm having a hard time coming up with a good excuse on why we can't book.

Example 2: My boss asked me if I'm interested in heading a project that calumniates with a big, labor intensive event in April 2013, when I'm hoping to be either very pregnant or on maternity leave. I feel bad taking on the project when I will (hopefully) have to transition it close to the event. I'd rather someone else take it. Passing wouldn't negatively affect my career in any way, but I can't think of a good reason to tell him why I want to pass.

Has anyone else had to give excuses for not participating in things because they were TTC? What did you say??
