You are 3 weeks and 4 days

Do you feel different? You may find yourself analyzing every twinge for signs that you're pregnant.

255 days until your due date

It's still very early, and you probably won't have symptoms yet, although you may have some light spotting. Some women say they "feel" pregnant or just "know" before their breasts change or they feel sick. You may be very in tune with your body and notice changes before you can take a test.

But your mind can play tricks on you: you may want to be pregnant so much that you convince yourself you feel different. And if you don't feel any different, that's completely normal too.

Either way, the only definite way to know is a pregnancy test. You don't need your doctor to confirm it, since they use the same tests you can buy over the counter. If the test is positive, you're pregnant!

Nutrition: Diet ban

If you were dieting before you conceived, don't carry on once you're pregnant. Dieting can leave your baby undernourished and more likely to be born early and underweight. Do eat a healthy, balanced diet, and avoid junk food, which can raise the risk of your baby developing weight problems.

If you're overweight or obese, your doctor may recommend gaining less weight than other women: 15–25 lb if you're overweight and at least 15 lb if you're obese, compared with 25–35 lb for women of normal weight.

Ideally, lose excess weight before conceiving, because obesity makes diabetes and high blood pressure more likely and increases the chance of needing a cesarean.

Ask a Nutritionist

Should I give up coffee in case I'm pregnant?

The March of Dimes advises women who are pregnant or trying to conceive to have no more than 200 mg of caffeine a day, about one 12-ounce cup of coffee. High doses can increase the risk of miscarriage; one study found women who had two or more cups of coffee (or the caffeine equivalent) were twice as likely to miscarry as those who gave up caffeine. Be aware that decaffeinated drinks may raise cholesterol. The good news is that many women naturally go off coffee in early pregnancy.

This is general information based on NHS guidance, not medical advice, and every pregnancy is different. Talk to your midwife or GP about anything that worries you. If your baby's movements slow down or change, or you have bleeding, severe pain or leaking fluid, call your maternity unit straight away. In an emergency, call 999.
