Why It Matters to Understand Your Pregnancy Timeline

If you've recently found out you're pregnant and you're not sure what to do next, you're not alone. Many women feel overwhelmed in these early moments.

Knowing how far along you are can help you:

Understand what your body is experiencing physically and emotionally
Know what medical care you might need right now
Explore your options, including parenting, choosing adoption, or other paths

Doctors use the first day of your last menstrual period (LMP) as the starting point, even though you don’t conceive until around two weeks later. This method is widely accepted and gives a consistent way to date a pregnancy.

But if you don’t remember the date of your last period, or if your cycle is irregular, that’s okay. There are still safe, reliable ways to estimate how far along you are—many of which are free and available locally.

Knowing your gestational age won’t solve everything—but it’s a powerful first step that can give you a sense of direction and control.

How Do Doctors Count Pregnancy Weeks?

It may sound strange, but medical professionals start counting your pregnancy from the first day of your last period, not the day of conception. This method works well for most people because it’s easy to track and offers consistency in care.

Here’s a quick breakdown:

LMP (Last Menstrual Period): Day one of your last period
Ovulation: Typically around day 14 of a 28-day cycle
Conception: Usually occurs shortly after ovulation

This estimate assumes a regular cycle, which not everyone has. If your cycle varies, that’s okay—there are ways to get a clearer picture.

A first-trimester ultrasound can confirm or adjust your due date. It’s especially accurate before 13 weeks and measures your baby’s size to estimate gestational age.

Doctors may also use:

Blood tests to measure hCG hormone levels
Pelvic exams to check the size of your uterus
Listening for a heart tones, which usually become audible by 10–12 weeks

All of these are helpful, especially if you’re unsure of your cycle.

Curious about your first appointment? Here’s what to expect.

Estimating How Far Along You Are at Home

You don’t have to wait for a doctor’s visit to get a rough idea of how far along you might be. There are simple tools and signs you can use right at home.

1. Think Back to Your Last Period

Try to remember the first day of your last period
Count the weeks from that day to today
That gives you your estimated gestational age

This works best with a regular cycle. If that’s not you, don’t worry—try the next method too.

2. Match Your Symptoms to Common Pregnancy Stages

Here are some general timelines for common early pregnancy symptoms:

Weeks 4–6: Missed period, tender breasts, fatigue, frequent urination
Weeks 6–8: Morning sickness, mood swings, heightened sense of smell
Weeks 9–12: Food cravings, bloating, light spotting, strong emotions

Everyone’s experience is different, but tracking your symptoms in a notebook or app can help you see where you might fall in the timeline.

3. Use a Digital Pregnancy Calculator

Online calculators and apps can help you estimate your due date and how many weeks pregnant you are. All you need is the first day of your last period.

These tools give helpful overviews and milestones—but remember, they aren’t exact. Only a provider can confirm things with certainty.

What If I Don’t Remember My Last Period?

Not sure when your last period started? That’s very common—especially if your cycles are irregular or you weren’t tracking.

A first-trimester ultrasound is one of the most accurate ways to date your pregnancy. It uses the baby’s size—specifically crown-rump length—to estimate how far along you are.

Your doctor may also:

Ask about your symptoms
Run a blood test to check your hormone levels (like hCG)

Even if you don’t have exact dates, there are safe, proven ways to figure things out.

Considering Adoption Later in Pregnancy

Even if you're far along, adoption is still an option. You can make an adoption plan at any stage—whether early in pregnancy, later on, or even after delivery. There’s no deadline for choosing what feels right for you.

First Trimester (0–13 Weeks)

You have more time to consider your options carefully and make a plan that fits your needs.
This stage allows for more opportunities to explore adoptive families and begin building a relationship if you choose.
With early planning, you have maximum flexibility in deciding how much future contact you'd like, such as updates, visits, or ongoing communication.

Second Trimester (14–27 Weeks)

You still have plenty of time to create a thoughtful adoption plan and receive full support.
During this time, many women benefit from counseling that helps them explore their emotions and goals without pressure.
You can still choose an open, semi-open, or closed adoption—whatever feels best for your comfort and privacy.

Third Trimester (28 Weeks and Up)

Adoption remains a fully available option, even if you are close to your due date or already in labor.
Agencies experienced in late-term and hospital adoptions can respond quickly, helping you build a plan in just hours if necessary.
You'll be supported by professionals who can walk with you through labor, placement, and the emotional days that follow, with care and respect.

Many women make an adoption decision late in pregnancy—or even after birth. No matter when you decide, it’s never too late to choose what’s right for you and your baby.
