About this symptom


Difficulty falling asleep or staying asleep in early pregnancy can have several different causes. One being hormones, as with so many others, the rapid influx of hormones can wreak havoc with your sleep cycle. Progesterone is a natural sedative, and causes feelings of exhaustion that often leads to daytime napping, which then disrupts regular sleeping patterns. As blood volume increases the body needs to filter more fluid which leads to more frequent urination and interrupted sleep. Sleeplessness may also be caused in part by stress or physical discomfort.

Includes: Trouble falling asleep, or staying asleep. Restlessness.

Unable to sleep since 12dpo, now 14dpo. But I wonder if it's because my husband has been working at night these past few days.
