Phy, I totally relate to the idea of planning things out, and am impressed by your capacity to juggle so much stuff at once. But a few thoughts to maybe keep in mind:
1- pregnancy itself can be pretty tiring, particularly at the beginning. Why, I don't know. But you should be aware that there may be parts of it when you're pretty low energy, and may have less capacity to get stuff done than at other times of your life.
2-pregnancy can be hard and stressful to plan. It may happen when you want, and it may not. So just be careful not to get your heart absolutely set on a particular schedule that you may, through no fault of your own, not be able to implement.
3- and mostly, best wishes for it all; hope you come through the many challenges ahead well.
