What are the symptoms of pregnancy before your missed period?

Some common early pregnancy symptoms before a missed period may include:

1. Implantation Bleeding: Light spotting or bleeding that occurs around the time the fertilized egg implants in the uterine lining, usually around 6-12 days after ovulation.

2. Breast Changes: Your breasts may become sore, swollen, and tender. The nipples may darken or feel more sensitive.

3. Fatigue: Extreme tiredness and exhaustion for no apparent reason may be an early sign of pregnancy.

4. Nausea and Vomiting (Morning Sickness): Though typically associated with later pregnancy, some women experience mild nausea or morning sickness early on.

5. Bloating: Increased progesterone levels can lead to gas and bloating in the early stages of pregnancy.

6. Mild Cramping: Mild uterine cramps similar to those around period time may occur.

7. Frequent Urination: As the pregnancy progresses, your body produces more blood, which needs to be filtered by the kidneys. Increased urine frequency might result from this process.

8. Heightened Sense of Smell or Taste: Changes in hormonal levels can make your sense of smell and taste more acute, causing sensitivity to certain scents or foods.

9. Food Cravings and Aversions: Unexplained changes in food preferences can also be an early pregnancy clue.

10. Mood Changes: You might experience occasional mood swings due to changing hormone levels.

Please note that the presence or absence of any of these symptoms doesn't necessarily indicate pregnancy, as several other factors (like stress or hormonal imbalances) can cause similar effects. Additionally, some women may not experience early signs at all.

A pregnancy test (usually based on detecting a pregnancy hormone called Human Chorionic Gonadotropin or hCG in the urine or blood) can confirm pregnancy. For the most accurate results, it's best to take a pregnancy test a few days after your missed period.
