Learn about our Medical Expert Board Print People who can become pregnant may wonder about early signs or symptoms of pregnancy. For instance, can insomnia be one of these early symptoms? Insomnia Insomnia is a common sleep disorder that occurs when someone has difficulty falling or staying asleep. Difficulty falling or staying asleep commonly affects pregnant and non-pregnant people alike. So is it a reliable indicator of pregnancy? This article explains how sleep may change with pregnancy and whether insomnia is a sign of being pregnant. Verywell / Brianna Gilmartin Learn About the Consequences of Lack of Sleep During Pregnancy How Sleep Changes Early in Pregnancy The first trimester of pregnancy includes many changes that affect a person's body, some of which occur soon after conception. A handful of these adjustments can also interrupt sleep in pregnancy. Therefore, some of these early shifts can lead to insomnia. People in the first 12 weeks of pregnancy commonly experience fatigue and excessive daytime sleepiness. Some other signs of tiredness include: Poor concentrationImpaired job performanceIncreased likelihood of accidents Sleepiness affects up to 37.5% of pregnant people at 6 to 7 weeks. That's because the increased levels of the hormone progesterone cause drowsiness. In addition, progesterone often leads to increased sleep interruptions, which may affect overall sleep quality. Moreover, some other early pregnancy symptoms can also disrupt sleep. These include: Morning sickness Needing to urinate more frequently, including in the night Back pain Breast tenderness Increased appetite Anxiety By week 10 of pregnancy, people spend more time sleeping. Often this means a longer sleep duration overnight, and sometimes it includes napping during the day. This increased sleep is because sleep is more disturbed by frequent awakenings, and deep sleep decreases. Many pregnant people complain that they get poor quality sleep during this period. Fortunately, rest tends to improve in the second trimester. However, sleep tends to worsen again with the physical discomfort of late pregnancy. Recap Hormonal changes in early pregnancy can impact a person's sleep. In addition, other early pregnancy discomforts can interrupt sleep, which can lead to insomnia. Can Insomnia Be a Sign of Pregnancy? Even though insomnia is a common occurrence during pregnancy, it is not a reliable early indicator of pregnancy for a couple of reasons, including: It may not occur often or early enough to be an actual physical sign of being pregnant. Insomnia is the most common sleep disorder, affecting millions of people of all genders and ages. Consequently, insomnia should not be relied upon as a sign that a person has become pregnant. Getting Help for Insomnia If you have insomnia, no matter the reason, you should seek help to sleep better. For temporary relief, you can use over-the-counter (OTC) or prescription sleep medications. However, you should not use these for longer than a few weeks. Also, if you think you may be pregnant, you should avoid them altogether. Instead, take a home pregnancy test or see your healthcare provider to be sure. Then seek out alternate options for persistent sleep difficulties. Sleep Study If your trouble sleeping persists, seek an evaluation by a board-certified sleep physician. If needed, your doctor can arrange a sleep study to identify the causes of the disturbance, such as sleep apnea. In addition, they can sort out contributions from stress, anxiety, pain, and other issues. Fortunately, if a sleep disorder is contributing to insomnia, effective treatment may quickly resolve the condition. Therapy Since some medications may not be safe to use during pregnancy, you may want to try other solutions. Cognitive behavioral therapy for insomnia (CBTI) is an attractive option to fix the condition without relying on sleeping pills.

Summary While insomnia is common in early pregnancy, it is not a reliable indicator that you could be pregnant. That's because insomnia can affect anyone for a variety of reasons, pregnant or not. A Word From Verywell If you are suddenly struggling with insomnia, you may be wondering if it could be because you are pregnant. That's understandable since hormonal fluctuations and early pregnancy discomforts can lead to sleep disruption. However, insomnia is not an accurate indicator of pregnancy, so if you are struggling with sleep, take a pregnancy test to be sure. Then seek out support from your healthcare provider to address your sleep issues. 5 Sources Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
