What's happening in my body?

You could be starting to get a bit puffy and swollen in your face, hands and feet. This is probably completely harmless and caused by water retention – but do mention it to your midwife or doctor.

They will want to check your blood pressure, just in case it's a sign of a dangerous condition calledpre-eclampsia.

Pre-eclampsia can happen in the 2nd half of pregnancy or after the baby is born. If you get any other signs, such as splitting headaches, vision problems, or pain just below the ribs, then call your doctor, midwife or NHS 111.

Feeling gassy after eating

Are you burping a lot? It's very common around now. You may be feeling more full than usual.

After eating or drinking you could get:

• burning in your chest
• bloating
• nausea

This is probablyindigestion and heartburn. Digestive problems are caused by your growing baby taking over some of the space where your stomach used to be.

It can help to:

• eat smaller meals, so you don't feel too full afterwards
• eat healthilyand avoid rich, spicy and fatty foods
• cut back on drinks with caffeine (such as tea, coffee and energy drinks)
• sit up straight when you eat
• give up alcohol and cigarettes

If you're pregnant and single

Around1 in 4 families are single parent families. You may be worried about money or how you'll cope. It's important that you talk to people about how you feel and ask for help if you need it.

You can also talk to your doctor or midwife about local support groups.Gingerbread is an organisation for single parent familiesthat can advise you on everything from benefits to childcare.

Get more advice on being a single parent on the NHS website.

What does my baby look like?

Your baby, or foetus, is around 34.6cm long from head to heel, and weighs about 660g. That's approximately the size of a head of cauliflower, and the weight of 4 jacket potatoes.

This is an active time for your baby. A loud noise could make your baby jump and kick, which shouldn't hurt, but might take you by surprise. You might even feel the occasional hiccup.

Your baby is now peeing into the amniotic fluid. By now, most of the liquid around your baby is urine which provides cushioning and helps keep the temperature snug and stable.
