Slightly confussed with when the second tri starts my app and midwife and everyone i know says 13 weeks, but this site says 14 weeks.
anyway seeing though most say 13 weeks, i though i'd post a pick of my 8 weeks and 13 weeks bump. i think 8 weeks is mainly bloating as taken in the evening as my 13 week bump i've only just taken and it's 4pm here. please ignore the underwear in the first pic, was taken just before going to bed.
I starts with the beginning of week 14, completion of week 13.
Welcome to the second tri!
I wondered the same thing because I always thought it was at 12w but then I saw different ladies posting different things.
Depending how you and your OB or MW calculate trimesters they can begin at different times, I think the development method is most common (at least where I am)
Here's the info I found:
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.
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.
