Pregnancy symptoms

• Spotting

About five to 10 days after conception, some women notice light spotting when the embryo implants in the uterus. So if you’ve had a light period this month, you might still be carrying a little bundle of joy.

• Fatigue

Many women feel very tired early in pregnancy (it takes lots of energy to create a baby!). In fact, fatigue is often one of the first signs of pregnancy. If you are pregnant, chances are you'll start to feel less tired around week 12, when the placenta is fully formed.

• Urinary frequency or constipation

Nausea is one of the most common side effects of pregnancy. It’s caused by an increase in hormone levels (about 80 percent of women experience "morning sickness" during the first 3 months of pregnancy). For many, this nausea is not necessarily confined just to the morning – some feel it all day long. Click here for all the facts on morning sickness.

Pregnant bodies are working hard to grow that baby, and need about 300 extra calories a day. Some women find themselves craving food they would never normally dream of eating, while others simply feel hungry all day long.

• Headaches

The frequency of migraine headaches can increase with pregnancy. Many women who get hormonal migraine headaches find they get more of them during especially early in pregnancy, explains Pitman. However, some people have the opposite experience and actually get a little reprieve from migraines while expecting.

• Mood swings

Many women experience emotional mood swings throughout pregnancy. It's natural to go through a variety of emotions as hormones are adjusting and the body is changing.
