@stellabella:  6 weeks would be the estimate used by your doctor until the baby is large enough to be measured using US.

They use the first day of your last menstrual cycle as Day 1.  So if the first day of your last menstrual cycle was October 3, 2013, then your current EDD would be July 10, 2014.  You will be 8 weeks along when you see the doctor.

@stellabella:  The Clear Blue test only estimates how pregnant based on the level of HcG in your urine.  The doctor will use the first day of your last menstrual cycle to set an estimated due date (EDD) and all milestones of your pregnancy will be based on that initial EDD.

What do you mean push things back by 2 weeks?  Unless you were blood tested every day during your cycle you won’t really know exactly which day you conceived or implanted; they are merely estimates based on the first day of your last menstrual cycle.

This is also why everyone says pregnancy actually lasts 10 months instead of 9.

Hence 40 weeks.  Smile

The standard is to count your pregnancy from the first day of your LMP — so basically, by this measure, you are already 2 weeks pregnant when you conceive. So you’re 6 weeks right now. Doctors do this because the only thing they know for sure is the date of your LMP — ovulation date, implantation date, etc. are (generally) all estimates. 

Also, congrats!

I get where you’re going with this.  You are currently 6 weeks pregnant but the baby is likely 3-4 weeks old.  You have to stop thinking about it from the point of view of the baby.  Pregnancy calculations are based on mom’s menstrual cycle.  That is why they say you are 6 weeks pregnant.  Counting the baby’s age doesn’t kick in until the baby is born.

@stellabella:  I’m not aware of any “pushing back” of time periods.  The only time they measure from is first date of your LMP.  40 weeks after my LMP was April 15th, so that was my due date.  Then, I had my first ultrasound and the baby was a little bit bigger, so he changed my due date to April 9th.  Its not like it changes how far along you are, its just that baby size is a better indication of when it should be born than exactly 40 weeks from your LMP (which is a very dated way of guessing due dates that started in the 1700’s).

Does that make sense?  I’m no expert, I’m just letting you know what my personal experience was with my doctor and how he explained it to me!

@stellabella:  Doctors typically go by your LMP, so I would go by that. As for the Clear Blue, I don’t know, but I personally wouldn’t go out and get a test if I already know I’m pregnant just so it will tell me how far along I am. Once you verify you’re pregnant, make a prenatal appointment and go by what your doctor says. They MAY change the date depending on how your baby is growing. Typically if baby is within a week growth, they won’t change the date. It’s all based on growth and not the “age” of your baby as your baby doesn’t have an age until it is born.

They’ll do your EDD based on LMP, but can adjust the due date if an ultrasound shows the baby growing ahead or behind by more than a week (like for people with PCOS their LMP might have been 3 months ago but because they don’t ovulate predictably they may only be a month along so they adjust the due date)
