How Far Along Am I In My Pregnancy

How Far Along Am I In My Pregnancy

It can be hard keeping up to date with the weeks and months of pregnancy but by using our how far along am I calculator you can quickly check without the guesswork.

Each calculation will give you specific information about the:
Week you are in
Month you are in
Trimester you are in
The day a new week begins for you

How far along am I, a question asked frequently by pregnant mothers, refers to the amount of time that has elapsed since the start of the last menstrual period (LMP) and generally not to the amount of time since baby was conceived. Pregnancy is normally counted from LMP which is about two weeks before baby is actually conceived.

When calculating an estimated due date, calculators and tools often base the date on the first day of your last menstrual period. Do you know the first day of your last period? That was day one of week one. So by the time you find out you’re pregnant, you’re usually already four weeks pregnant, which is when your next period would have been due.

Pregnancy lasts for an average of 40 weeks, however 37 to 42 weeks of pregnancy is considered as full term. After 42 weeks of pregnancy, usually a doctor or midwife will want labour to get going. When you’ve worked out your estimated due date, remember it’s exactly that – an estimated date. Around 40% of babies are born before the estimated due date, and around another 40% are born in the two weeks after. Only 3-5% of babies are born on the actual estimated due date.

What if I don’t know the date of my last period or if I have irregular periods?

The due date calculation works best if your menstrual cycle is regular and your periods are every 28 days.

If you have an irregular menstrual cycle, you may not know the date of your LMP. And if your cycle varies in length, counting from the first day of your LMP may not give you a date you can rely on.

Your first ultrasound scan, called your dating scan, will give you a more accurate due date for your baby. The person performing the scan (sonographer) will measure your baby from his head to his bottom. This is called his crown rump length (CRL), and it gives a more accurate idea of how far along your pregnancy is.

You should be offered a dating scan when you’re between 10 weeks and 13 weeks plus six days pregnant, based on your LMP.

What is a trimester?

If you are a pregnant mother or involved father and sign up for classes at the PHI Center in anticipation of your baby’s birth, we’ll put you a class based on your trimester. We offer classes for first, second or third trimester parents so you’ll learn specifically about what’s happening in your pregnancy. If you’ve been seeing a doctor you’ve probably heard the word “trimester” spoken dozens of times, but do you know what it means? Do you know how we got that term and why we use it? Let’s learn together.

The American school system made popular the word semester. Most schools divide their academic year into two “semesters,” but how does that help us understand a trimester? The answer’s found in the etymology of the word.

Technically, semester is a German word derived from its older Latin cousin “semestris.” That word comes from two smaller Latin words, “sex” which means six, and “mensis” which means month. In the German school system Semester is used literally; they have two six-month semesters. In America the semester doesn’t represent six months, instead it represents dividing one period of time into two equal parts (The academic semester is closer to four months). For a pregnancy it’s a little simpler, trimester comes from two words as well: “tri” meaning three, and “mensis” meaning month. Trimester literally means three months. As an aside, the term menstrual also comes from this Latin word “mensis,” and simply refers to a monthly cycle. Your pregnancy is divided into three, roughly three-month periods called trimesters.

The key to understanding trimesters and your due date is accepting it’s not an exact science. The 280 day (forty week) gestation period is derived from an average. The due date of a baby has a give or take of up to two weeks based on when conception happened. And we can’t forget some months have five weeks while others have four. At the Phi Center, we’ll utilize your last menstrual period (LMP) to estimate your due date and calculate which trimester you’re in.

How long is each trimester?

There’s no official definition, but the trimesters are generally considered to be about three months each. At BabyCenter, you graduate to the second trimester the day you turn 14 weeks pregnant. The third starts the day you turn 28 weeks pregnant.



Does pregnancy really last nine months?

Of course pregnancy is nine months long, right? Well, not exactly. For example, if your LMP started on January 1, your due date would be October 8 – or October 7 if it’s a leap year. So that’s more like nine months and one week. (And it’s even longer if you go past your due date.)

Isn’t a month four weeks long?

Actually, the only month that’s four weeks (or 28 days) long is February – that is, when it’s not a leap year. All the others are either 30 or 31 days. So, on average a month is 30.4 days long – or 4.3 weeks.


EDD is an abbreviation for estimated due date.

LMP is an abbreviation for last menstrual period, which is the first day of your last period.

Gestational age is the age of pregnancy when counted from LMP or two weeks before conception.

Fetal age is the age of pregnancy when counted from Conception.

How Long is Pregnancy?

Pregnancy – from start to due date – is either 40 or 38 weeks’ long, depending on the start date used.

Counting from LMP: Pregnancy is 40 weeks from the first day of the last menstrual period (LMP) to the estimated due date. This method of measuring pregnancy adds an extra two weeks since counting starts approximately two weeks before baby is conceived.

Counting from conception: Pregnancy is 38 weeks from conception to estimated due date.

Actual length of pregnancy: The actual length of pregnancy varies greatly among women. Just 4% of babies are born on their due date while 70% are born within 10 days of the estimated due date. The remaining 30% are born more than 10 days before the due date or more than 10 days after the due date.

How Many Weeks Am I?
To calculate how many weeks pregnant you are, start by counting the recurring first day of your last menstrual period until the present time (do not count the day of your LMP). The number of recurring days you count is the number of weeks you are now.

If your last menstrual period started on a Wednesday, count one week to the next Wednesday. Now keep counting Wednesdays until you reach the present date.
LMP = December 2, 2015
Current Date = February 4, 2016

1st Wed = December 9, 2015 = 1 Week
2nd Wed = December 16, 2015 = 2 Weeks
9th Wed = February 3, 2016 = 9 Weeks
You are 9 Weeks and 1 Day pregnant

Another method to calculate how many weeks pregnant you are, is to count the days from the first day of your Last Menstrual Period (LMP) until you reach todays date. Once you have counted all the days that have passed since your LMP divide the counted days by 7.

The answer will be how many weeks you are now.

How Many Weeks Am I Formula: (LMP + Days Passed Since LMP) / 7
LMP = Last Menstrual Period
Each of these methods will give you the gestational age of your pregnancy.

How Many Months Am I?
To calculate how many months’ pregnant you are, start from the first day of your last menstrual period, then count forward one month and repeat until you reach todays date.

LMP = December 2, 2015
Current date = February 4, 2016

1 month = January 2, 2016
2 months = February 2, 2016
Months counted = 2. You are 2 Months and 2 Days pregnant.

If your LMP date falls on a day after the 28th and the numerical day of your LMP is not in the month you are counting, then you must count to the last day of that month.
LMP = January 30, 2015

1 month = February 28, 2016
2 months = March 30, 2016
3 months = April 30, 2016
And so on..
Note: Our months are calendar months but in the pregnancy world a month may be any of the following:

4 weeks
5 weeks
A lunar month
Any reference to how many months pregnant you are contains this uncertainty unless the type of month is specified.
