What are the different trimesters of pregnancy?

A pregnancy can be divided into three trimesters. The first is week 1 through week 12. The second is week 13 through week 26. The third is week 27 to the termination of the pregnancy.



People also ask: Which trimester is most important?

The most important time of your pregnancy is the first trimester. The fetus is approximately 4 inches long at the end, and weighs less that 1 ounce. However, all its functions have started to form major organs and nervous systems, heartbeats, arms, legs, toes and hair, as well as buds for future teeth.

Second, how many weeks is each trimester? The first trimester lasts approximately from weeks 1-13; the second trimester lasts about week 14-week 27; and the third trimester lasts around week 28-week 40 (and higher).

What is the first trimester of pregnancy, other than what I have just said?

What is the last organ that a baby develops?
