What are the symptoms of being pregnant?

Early Signs of Pregnancy: What to Look For

One of the first clues that you might be pregnant is a missed period—especially if your cycle is usually regular. While a late period can happen due to stress, diet changes, or hormonal imbalances, when combined with other symptoms, it can point to pregnancy.

Nausea and vomiting, often called “morning sickness,” is another common early sign. Despite the nickname, this queasiness can strike at any time of day and typically begins around week six of pregnancy. Not every woman experiences it, but for those who do, it can range from mild queasiness to more persistent discomfort.

Many women also notice breast changes early on. Your breasts may feel fuller, tender, or even tingly. This happens as hormone levels shift to prepare your body for potential breastfeeding. The sensitivity can feel similar to premenstrual symptoms, but if it lingers longer than usual, it could be a sign of pregnancy.

Feeling unusually tired is another clue. In early pregnancy, your body starts working harder, increasing blood volume and adjusting hormone levels—especially progesterone, which can have a sedative effect. This metabolic shift often leads to sudden exhaustion, even in the first few weeks.

Another telltale symptom is frequent urination. As the embryo implants and the uterus begins to grow, it puts pressure on the bladder. Plus, increased blood flow through the kidneys causes the body to process fluids more quickly. This can start as early as six to eight weeks into pregnancy.

Keep in mind that many of these symptoms overlap with premenstrual changes or even illness and stress. The only sure way to confirm pregnancy is with a test—especially if your period is late and you're noticing several of these signs together.
