sorry girls. this has probs been posted before and probably just shows me up as being stupid

but am getting confused about how many months pregnant compared to how many weeks pregnant! Just read a post which says 18 -22 weeks are 5 months, whereas I would have presumed 20 weeks was 5 months? just wondering how the pregnancy books work out 18-22 wks=5months?
THanks!
