• You may be getting a bit of heartburn and indigestion. That’s your growing baby and hormones creating havoc with your digestive system.

• Your back will also be under strain; thanks to all the extra weight you’re now carrying around. It won’t help that your joints and ligaments are also looser than usual.

• Your ankles, feet and face could be puffing out a bit, particularly when it’s hot. This is probably due to water retention, but get it checked out, just in case its pre-eclampsia. This is a condition where you may feel perfectly well, but then your blood pressure can get dangerously high, very quickly.

• A quick-fix for many niggling conditions in the third trimester is to put your feet up. But if you are worried about anything at all, then talk to your midwife or doctor.

You may start getting new symptoms now, such as indigestion.

Your signs of pregnancy could also include:

• sleeping problems

• stretch marks

• swollen and bleeding gums

• pains on the side of your baby bump, caused by your expanding womb (’round ligament pains’)

• piles

• headaches

• backache

• indigestion and heartburn

• bloating and constipation

• leg cramps

• feeling hot

• dizziness

• swollen hands and feet

• urine infections

• vaginal infections

• darkened skin on your face or brown patches – this is known as chloasma or the ‘mask of pregnancy’

• greasier, spotty skin

• thicker and shinier hair

• symptoms from earlier weeks, caused by pregnancy hormones, such as mood swings, morning sickness, weird pregnancy cravings, a heightened sense of smell, sore or leaky breasts, a white milky pregnancy discharge from your vagina and light spotting (seek medical advice for any bleeding)

Your baby, or foetus, is around 37.6cm long from head to heel, and weighs about 1kg. That’s approximately the size of a pineapple, and the weight of a big bag of brown sugar.

Your baby’s heart rate is changing all the time. Around week 5 or 6, when it was first detectable, it was around 110 beats per minute (bpm). Then it soared to around 170 bpm in week 9-10. Now, it’s slowed down to around 140 bpm and it will be around 130 bpm at birth. That’s still a lot faster than your heart rate, which will be around 80-85 beats per minute. This is partly because babies’ hearts are so small that they can’t pump much blood, but they can make up for this by going faster. It also helps to keep them warm.
