Is 2nd trimester defined as 12 weeks or 13 weeks? I forget..

Either way I was 12 weeks Saturday so Im either in my 2nd trimester or Ill be there on Saturday.

TMI Warning!!

 

I'm at 12 weeks and I woke up on Saturday hornier than I've been in MONTHS. So I don't know what the technical definition of 2nd trimester is, but my libido is definitely there! WOO! :)

I actually thought week 14? But maybe that just means 13 weeks, 1 day so that you're IN your 14th week? Or maybe I'm wrong. lol

 

I remember being confused last pregnancy about the timing as well...I went with 13 weeks that time ;-)

Okay, I'm not alone in my "when does the 2nd tri start?" confusion. First time around I had it in my head as 12, but if you divide 40 weeks it's 13 1/3. Which makes a lot of sense, because I didn't start to feel better until 14 weeks. So I think I'm going with 14! That's just over three weeks for me. We haven't told anyone except for parents & siblings and I don't want to until the second tri, that's why it's a biggish deal to me. I was going to try to wait until the anatomy scan but I don't think I'm going to be able to hide it that long this time...

Yes, it is confusing!  Below is a great article about the 3 diff. ways to calculate the trimesters.  The site also has a great Trimester Calculator that calculates all three theories at once  for you. For this thread's purposes, just go with whatever makes sense to you. I'm going with 14 weeks only because if I start telling others I'm in the 2nd trimester and they ask how many weeks I am...there is no confusion and explaining! Trimester Calculator.

 

The three basic ways to calculate trimesters

 

There are basically three ways of dividing up a pregnancy into the three trimesters; they are by:


Development,   Gestation,   Conception. They give different dates for when the second trimester begins and for when the third trimester begins. Your health care provider might prefer to use the Development method, while another Midwife or Doctor may use the Gestation method.


I am sure they do that just to confuse pregnant women.  Big Grin

 

by Development:

 

This uses actual developmental stages to divide up a pregnancy. From LMP to 12 weeks the embryo develops all the major organs and becomes a fetus. From 12 weeks to 27 weeks the fetus continues developing and reaches viability. From 27 weeks on the fetus finishes development and prepares for delivery. Here the second trimester begins at 12w 0d and the third at 27w 0d.

 

by Gestation:

 

With this method you take the 40 weeks of gestation and divide into three equal stages. Here the second trimester begins at 13w 3d and the third at 26w 6d.

 

by Conception:

 

This method is where you take the 38 weeks of post conception development, divide by three, into the three equal trimesters. Here the second trimester begins at 14w 5d and the third at 27w 3d.
 


What is the length of the first, second and third trimesters?

 

The length of the trimesters is often a source of confusion. The word trimester means 'three months'. Three periods of three months each, gives pregnancy a beginning, a middle and an end period.

These periods match the developmental stages to divide up a pregnancy

.

  • Beginning: From LMP to 12 weeks the embryo develops all the major organs, becomes a fetus, and the placenta takes over control.
  • Middle: From 12 weeks to 27 weeks the fetus continues developing and reaches viability.
  • End: From 27 weeks on the fetus finishes development and prepares for delivery.

 

When does the first trimester end or third trimester begin?

 

Does it really matter exactly when you are out of the first trimester or start the third trimester? No. When the trimesters start and end depends on who you ask, which book you read or what website you visit. Most health care providers actually talk about your pregnancy in weeks, rather than months or trimesters.

What's weird about the above article is that they don't cover the exactly at 14 weeks way of determining the second trimester.  I have no idea the reasoning behind that one...and that's the one I'm going with, LOL!

I thought it was nice at my midwife appointment today there was a paper in the info packet telling how they divide up the trimesters by week.  They count the second trimester as starting at 14 weeks.

I like 14 weeks because it gives me some hope that I'm getting over some milestone where this nausea WILL go away! winky.gif

post #12 of 17

I am a little over 12 weeks and already suddenly feeling better.  I don't have nausea if I don't eat every 10 minutes and I am not exhausted in the same way that I had been.  Yay! 

post #13 of 17

I like the 12 week answer :) I usually think of the 2nd tri as 13 plus weeks. I generally feel better about the pregnancy once i hit 12 weeks, though.

post #14 of 17
I'm 12 weeks on Saturday. I was feeling great from 10 1/2-11 1/2 weeks and then the last few nights I have been miserably sick again. So... I'm not sure my m/ s is gonna say goodbye with the 1st tri. Bummer. My only hope is that my body is busy creating some girls parts and that's why I still feel crappy. All my family is always sicker with girls. So I can hope!

I went with 12 weeks too, but I'm 14 weeks on Sunday so... I'll be in the 2nd trimester by all measurements.  Yippeeee!

post #16 of 17

I'm 12 tomorrow which is when I count it as at 12 weeks + a confirmed heartbeat I feel I can fairly safely publicly announce a pregnancy. :) So I guess I'm going by 'development'!

post #17 of 17

I felt a distinct shift around 12 weeks too, much more energy.  And the last few days I've barely even been nauseous.  Hooray for the second trimester!
