We have some mamas getting close and we will all be there by May 2nd!
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:
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.
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.
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?
These periods match the developmental stages to divide up a pregnancy
When does the first trimester end or third trimester begin?
lol and nice! I'm starting to get some libido back, too! Honestly, I'm feeling better and better everyday....my house is clean again, clean clothes for the family in the drawers, able to get up earlier, etc.....LOVING saying goodbye to the first trimester and hello to the second!!!! Yeah!
