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.

EDD 14 december
I think from 10-13 weeks it was at its worse and then I started getting one or two days where I didn't feel so ill? Now I'm still getting waves of nausea but not constant. 
ALL babies are PERFECT. Its so not right they keep pushing me. Luckily, after this week, it will no longer be an issue because they can't after 13 weeks or something and I don't see them until July. I really want to switch...but this hospital is SO close...literally a 10 min walk. I would have to commute 1 hr one way to go somewhere else...and it wouldn't be that bad...but considering how frequently I will be going...I dunno...it would be alot...
