mathematics Pregnancy can get confusing pretty quickly. Are you in week 12 or 13? The first or second trimester? Pregnant three months or four? Fortunately, the answer to the (relatively) simple once you know what to count. Here's what you need to know about how many weeks, months and trimesters in pregnancy - and where you fit
There are 40 weeks (or 280 days) of pregnancy, starting from the first. day of your last menstrual period. Keep in mind, however, that only about 30 percent of pregnancies will reach week 40. In fact, a full-term pregnancy is considered anywhere 39-41 weeks in length (which means babies born at 39 weeks is no longer "the beginning" of one born at 41 weeks ).
There are 13 or 14 weeks per trimester (just divide 40 by three and you'll see why the details are not right).
There are three trimesters in pregnancy: you, which lasted from about week 1 to 13; You, which lasted from about week 14 to week 27; and you, which lasted from about week 28 to week 40 (above).
Your 40 weeks of pregnancy was calculated as nine months. But wait ... there are four weeks in a month, which will make 40 weeks 10 months. Well? Not exactly. Four weeks is 28 days, but the month (with the exception of February, of course) have 30 or 31 days, to make each month about 4.3 weeks long.
If this explanation has a rotating your head, here is a simple solution of approximately how many weeks, months and trimesters are calculated in pregnancy:
doctor says you was 15 weeks pregnant, but you're also told that you are in week 16. which is it? Short answer: both. In both cases, your due date is the same - it's the language refers to the different
It turns out how many weeks into your pregnancy is slightly different from how many weeks pregnant you .. If you are in week 16, you are right -Right 15 weeks and a few days pregnant. Fifteen full week has passed, but not 16 weeks, so people say that you are both 15 weeks pregnant and in week 16 of pregnancy.
To clear things up, thinking about the anniversary. When you are born, you are not even old but in your first week of daily life. When you turn 1 year old, you have to live through the first year and start on your second. In other words, on the first anniversary of your first day you are in your second year. But no one said you were 2 years old until you've finished second and third year has started you. The same rule applies when talking about you: your x weeks pregnant, but in your x + 1 weeks of gestation
It is not yet checked by doc about.? It is calculated counting from your last menstrual period (LMP) is not the day you are pregnant. So try to remember the first day of your LMP and add 40 weeks to it.
