How many weeks am I really?

Ok, the first really confusing part when talking to your doctor is how many weeks are you pregnant?

Believe it or not, the weeks start counting from your Last Menstrual Period (LMP) ie. the last time you had a period. Forget that you conceived approximately 2 weeks after that, that doesn’t matter. So in actual fact, you get an extra 2 weeks of pregnancy for free!

So take that LMP date, add 40 weeks and voila! You have a due date. But I’m not actually going to be 40 weeks pregnant at due date, I’m only “really” 38 weeks. So do you take gestation as being “40 weeks” or “9 months”? Does 40 weeks sound like 10 months to you? Either way, it’s better than being an elephant!
