I go by weeks as well as everyone calculates different. When I want to say months, I give a month by counting back from my EDD. I'm almost into single digit weeks left, so I plan to start saying how many weeks I have remaining. One note on the Dr. Sears pregnancy book, they calculate weeks from ovulation date, not from LMP, so being 21 weeks according to the book is most likely 23 weeks according to most other calculations.
