How many weeks of pregnancy do i have left

Few things can compare to the rush and excitement of when you take a pregnancy test and read out the positive result! Once you’ve processed the news that you’re going to be a mom, your thoughts will naturally turn to planning and one of your first questions will no doubt be: when is my due date?

Use these three simple steps to find out how far along you are in your pregnancy:

  1. Figure out when was the first day of your last period or the exact day you conceived.
  2. Enter the relevant dates into the pregnancy week calculator.
  3. Then hit Find out now! to find out how far along you are. 

Keep in mind every pregnancy is unique and the result will be an estimation rather than a fixed date.

While it’s true that most pregnancies last 40 weeks, there are other factors at play which will determine your due date. Most expectant mothers don’t realize that both menstrual and ovulation periods count as the first two weeks of pregnancy. Many won’t be aware of their pregnancy until their first missed period, and by that time they could be up to five weeks in. That means that simply estimating nine months from the day you take a pregnancy test isn’t going to calculate your due date, and, even so, factoring in a few weeks here and there for ovulation won’t either.

Unless you can pinpoint exactly what point of your ovulation cycle you were in at the time of fertilization, it’s difficult to know how far along you are and what date you’ll meet your baby. Luckily, our Due Date Calculator can help.

Using both the date of your last period and the length of your regular cycle, or exact date of conception, our Due Date Calculator will quickly work out your estimated due date, tailoring it accordingly for longer, shorter, and average cycle lengths.

Once you’ve calculated your due date, you can get a better idea of when to expect your little one – and start to plan accordingly.

If you haven’t done so already, one of the first steps you should take is to schedule an appointment with your doctor, who can confirm that you're pregnant with a blood test and physical exam, and also help you establish a more precise due date.

At each following prenatal care appointment, you'll be examined to determine the size of your uterus, and to monitor your little one's development. Pregnancy milestones such as hearing your baby’s first heartbeat and seeing your baby via ultrasound will be a thrilling part of these checkups. Along the way, depending on what is observed, your pregnancy due date may be adjusted.

While your doctor will be able to advise you best, there are still plenty of things you can do as soon as you discover you’re pregnant. Explore the rest of our site to find out more.

If you've just found out you're pregnant, one of the first questions you'll have is: How far along am I? Beyond knowing that all-important due date, knowing how many weeks pregnant you are will help you better track those pregnancy milestones along the way.

How Can I Calculate How Far Along I Am and My Due Date?

If you know the date of the first day of your last menstrual period, or the date of conception, the easiest way to get an estimate of how far along you are is by using the Pampers due date calculator.

Keep in mind that your healthcare provider will be able to give you a more accurate answer at your first prenatal care appointment.

There are several different ways to figure out your due date and gauge how far along you are.

  • Last menstrual period (LMP): Pregnancy normally lasts about 40 weeks from the first day of your last period. Accordingly, the number of weeks that have passed since indicate what week of pregnancy you're in. To work out your likely due date, count 280 days (40 weeks) from the first day of your last period.

  • Date of conception: You probably conceived around the time of ovulation, which is around day 14 of the average menstrual cycle of 28 days. If you happen to know the exact date, count 266 days (38 weeks) to get an estimate of your due date. Alternatively, head to the Pampers due date calculator, where all the counting will be done for you.

  • Ultrasound: At some point during your pregnancy, you will likely have an ultrasound scan. This enables your healthcare provider to check on fetal growth and monitor other development milestones; it also provides the most accurate estimate for how many weeks pregnant you are and what your due date will be. This method is the most reliable, and particularly useful if you don't know the date of your last period or if your menstrual cycles are irregular.

When figuring out how far along you are, it can be confusing that the weeks of pregnancy are not the same as the gestational age of the baby. Remember, conception most likely occurred about 14 days into your last cycle, whereas pregnancy is calculated from the beginning of that cycle, so there's a two-week difference. For example, when you're six weeks pregnant, your baby's gestational age is only four weeks.

Can My Due Date Change?

During your prenatal checkups, your healthcare provider will monitor how far along you are. Don't be surprised, though, if your provider gives you a slightly different due date than the one you calculated.

Also, most babies don't arrive exactly on their due date. Every pregnancy is unique, and only a small percentage of babies are born right on time. Babies are typically born between weeks 38 and 42, and it's totally normal for your baby to arrive any time during this window.

If your baby is born pre-term, your doctor will be able to advise you on any extra care your baby might need. On the other hand, if your baby isn't born by the end of week 42, your doctor may suggest inducing the labor to bring on a vaginal birth, or he may discuss the option of a cesarean section with you.

What’s in Store for Me Until My Due Date?

Now that you know how far along you are, it might be helpful to know that pregnancies are often referred to in weeks and trimesters. Take a look at this pregnancy timeline for a breakdown of the weeks, months, and trimesters of pregnancy:

Here are some of the things you can expect in each trimester of pregnancy:

First trimester (weeks 0-13): You might notice some early signs of pregnancy, such as morning sickness and food cravings. Your provider will be able to confirm your pregnancy and set up your prenatal visits to make sure you and your baby stay healthy and safe.

Second trimester (weeks 14-27): This trimester is often referred to as the honeymoon phase of pregnancy. You may feel as if you have some extra energy to get things done, like baby-proofing your home, going to prenatal classes, and doing some gentle pregnancy exercise.

If you aren't already, this may also be a good time to start doing Kegel exercises to strengthen your pelvic floor muscles. You can do these simple muscle clenches anywhere, and they're beneficial not only during pregnancy and labor, but afterwards as well.

Third trimester (weeks 28-42): You're nearly there! As you get closer to the birth of your baby, you'll want to get prepared by making sure you have all the right baby gear. But remember to take the opportunity to slow down and rest whenever you can.

Now that you've learned how to know how far along you are and what important milestones await you during your pregnancy, remember that your baby will be here soon, and a new, exciting chapter is about to begin.
