Past me is Hilarious! What odd things did you do while TTC?

When I was TTC (for all of two months because I'm very fortunate) I was doing all sorts of calculations about how many viable eggs I had and weird stuff like that. I JUST found in my calendar for May 16th an event that's called "Unless you get pregnant the period closest to this one is your 200th." I think it's very sweet that past me wanted to celebrate this odd milestone. I DID get pregnant so I guess I'll just set it an appropriate number of months from now (26 day cycle) but now I'm curious if anyone else did odd things like this. Now that you are pregnant what do you think of yourself when you were TTC?
