You are 15 weeks and 1 day

Your bump may be clearly visible by week 16, and you'll be amazed at how fast it grows.

174 days until your due date

Around now, instead of just a slightly bigger waist, you may develop a definite bump and start to look pregnant. You may notice people's eyes drifting to your abdomen. If you'd rather keep it quiet in some places, such as work, wear baggy clothes.

Some women have neat little bumps at the front, while others spread out more. Yours will be unique, so try not to compare. Old wives' tales say carrying at the front means a boy and carrying over the hips means a girl, but this hasn't been proved.

If you haven't bought maternity clothes yet, you may want to buy some or adapt what you have.

A growing bump

Your belly may not be obvious in baggy clothes, but it will be quite prominent in fitted ones. Although your shape changes gradually, some women find their bump grows faster in some weeks than others.

As a matter of fact

Twin bonding

Twins bond well before they're born.

Advanced video technology has captured twins interacting in the uterus and even holding each other's hands.

Ask a Nutritionist

I keep waking up hungry at night. What should I do?

Night-time hunger is normal in pregnancy but annoying, especially if you're already sleeping badly. Head it off by snacking on the right foods before bed:

Eggs, milk (and so cheese and yogurt), and turkey are good sources of tryptophan, an amino acid that helps the body make niacin (a B vitamin), which in turn helps produce serotonin, a calming brain chemical that aids sleep.
Slow-release carbohydrates such as whole-wheat bread or pasta: for example, half a cheese or turkey sandwich, a little whole-wheat pasta with cheese, or a bowl of good whole-grain cereal with warm milk and honey will fill you up and help you sleep.
A handful of nuts and seeds, or plain yogurt with honey and fruit, are high in protein and will stop your stomach rumbling.

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.
