Ask any mama what she remembers about her first trimester, and she’ll probably start by listing her most salient symptoms. Pregnancy symptoms affect every person differently—and can even vary by pregnancy—but those early weeks and months are often a blur of morning sickness (more aptly named all-day sickness), constant headaches and food aversions. But it’s not like they’re all for naught. Those not-so-fun feelings are signs that your body is doing something pretty miraculous: starting to grow a baby. 

Here’s a list of the symptoms you can potentially expect in your first trimester and beyond, including some you’ve definitely heard about… and some you definitely haven’t.

Ectopic pregnancy symptoms

An ectopic pregnancy is defined as the case in which a fertilized egg implants itself anywhere outside of the uterus, most often in the fallopian tube. Because the fallopian tubes are not designed to carry a growing embryo, they are at risk of rupturing if the pregnancy goes undetected. While ectopic pregnancies are rare, they can be dangerous, requiring emergency treatment to manage potential internal bleeding. That’s why it’s so important to understand the specific symptoms that may present with this condition. 

Symptoms may be typical to those experienced in early pregnancy, but may also include the following: 

Common ectopic pregnancy symptoms

  • Vaginal bleeding
  • Pain in lower abdomen, pelvis and/or lower back
  • Dizziness or weakness

If the fallopian tube ruptures, additional symptoms may include

  • Sharp lower abdominal pain
  • Fainting
  • Low blood pressure
  • Shoulder pain
  • Rectal pressure

If you experience any of these symptoms, seek emergency medical care immediately.

First trimester pregnancy symptoms

Symptoms in the first trimester may be more pronounced versions of the early pregnancy symptoms, as your hormone levels increase over time to support the pregnancy and growing fetus. Morning sickness can be incredibly common—though some lucky ones may never experience it. If that’s you, just know that the absence of morning sickness is not a cause for worry.

Common first trimester pregnancy symptoms

Less common first trimester pregnancy symptoms

  • Breakouts
  • Constipation
  • Cramping
  • Dizziness
  • Heartburn
  • Mood swings
  • Spotting

Symptoms like cramping and spotting can be somewhat normal in the first trimester, as the uterus grows and expands. If you’re worried, reach out to your birth provider.

Coping with pregnancy symptoms

As you can see, pregnancy comes with a litany of symptoms, ranging from mildly annoying to pretty painful (swelling and back pain, we’re looking at you). 

Most symptoms are just that—symptoms of a normal pregnancy, markers of just how much change your amazing body is going through as you’re growing a new human. But if something you’re experiencing is causing you worry, trust your gut and reach out to your doctor or midwife. When it comes to your and your baby’s health, there are absolutely no silly questions. 

Now’s the time to start tuning into that maternal intuition, mama. It takes practice, but listening to what your body is telling you is always a smart idea. 

Frequently asked questions 

Q. When does morning sickness start?

Morning sickness (also known as nausea and vomiting of pregnancy, or NVP) typically starts around week six, with symptoms peaking around nine weeks. In many cases, morning sickness will start tapering off toward the beginning of the second trimester, around week 14.

Q. How soon can I take a pregnancy test?

The more advanced early home pregnancy tests can be used as soon as six days before your missed period (although their accuracy maxes out at 50% to 75%). If you can wait until the day of your missed period, the accuracy of these tests usually hits 99%. Your provider could always run a blood test, which can typically detect pregnancy as early as one week after conception.

Q. How do I calculate when my baby is due?

Calculating your due date can be done in several ways: using the first day of your last menstrual period, from which you’ll subtract three months, then add 7 days; or using a dating ultrasound, which are often administered transvaginally and allows a technician to measure the size of the embryo and estimate a due date accordingly.

Q. When should I announce my pregnancy? 

In short, it’s up to you! While traditionally, many pregnant people may choose to wait until the risk of miscarriage significantly decreases after week 13, plenty of others are choosing to announce that they’re expecting earlier, in the hopes of helping to normalize conversations around miscarriage and pregnancy loss. When you decide to announce your pregnancy is completely your decision.

Q. Should I choose an obstetrician or midwife?

Deciding to go with an OB/GYN or midwife depends on your personal circumstances, such as what types of providers have hospital privileges in your area, your own birth philosophy, where you plan to give birth and whether you’re considered potentially high risk for pregnancy complications. Ultimately, it may just come down to simply finding a provider that you feel comfortable with—which is where talking to friends and family members about the birth providers they used can be helpful.
