The Developmental second trimester starts at 12 weeks (third at 27 weeks), when it officially becomes a fetus and the scary miscarriage rates reduce.
The Gestational second trimester starts at 13 weeks + 3 days (third at 26 weeks + 6 days), which is the 40 weeks divided equally into three trimesters.
The Conceptional second trimester starts at 14 weeks + 5 days (third at 27 weeks + 3 days), which is the true pregnancy weeks (38) divided into three trimesters.
Okay, so I guess that's why there are some people that say it starts at 28 weeks. This whole time I've been planning for my whole life to pretty much change when I hit my third trimester, and I'd like to know what the magical date is, but I suppose Im just going to stick to 27 weeks, since that is what I came up with this morning.
Basically, I've been answering "When I hit my third trimester" to all of these things, and three weeks is a pretty big difference, IMO:
We've been living with my mom for about 6 months (primarily) with the intention of moving home
Ive been told by several twin moms to have pretty much all the big stuff ready by then
I am changing up some dietary differences as well as adding some supplements
I promised DH that I wouldnt pick DD up anymore since risks of preterm labor are higher for me
Basically, there are a lot of restrictions that Im going to be following in the 3rd trimester because I've read on numerous occasions that if you place the restrictions on yourself, there is less of a chance that you will get to the point where you have to go on bedrest.
