In fact, research suggests fundal height measurements are often off by two weeks in non-obese women. If your fundal height shows a discrepancy of more than three weeks at any point during your pregnancy, your health care practitioner may investigate the reason why.
Health care practitioners use the first day of your last menstrual period to get a general idea of when your baby is due, but conception could have happened earlier or later. If your practitioner thinks the original estimate was off, he or she may change your estimated due date. Rarely, measurements that are larger or smaller than expected may be linked to other conditions. Small measurements might indicate too little amniotic fluid or intrauterine growth restriction , while larger measurements may be a sign of uncontrolled gestational diabetes, a uterine fibroid or too much amniotic fluid.
If your practitioner suspects one of these causes, he or she may recommend an extra ultrasound or monitor your pregnancy more closely.

Your doctor or midwife will be able to double check this. Each contraction last around seconds and may be uncomfortable, but not painful. They might occur spontaneously, but can also be triggered by vigorous activity, sex during pregnancy or even just someone touching your bump.
If you experience regular or painful contractions, period-like pains or cramping at around 33 weeks pregnant or later, let your midwife or doctor know immediately as this could be a sign of labour.
Swollen ankles. At 33 weeks pregnant, your growing uterus may be putting pressure on the veins that move blood around your legs.
The resulting build-up of fluid can cause swelling in your feet, ankles and legs — a common complaint among mums-to-be. Take the weight off your feet as much as possible to prevent or ease the swelling, and wear comfy shoes and socks that don't pinch or squeeze your feet. It might seem counter-intuitive, but drinking plenty of water actually helps reduce water retention, so be sure to stay hydrated.
Normal swelling in pregnancy may be uncomfortable, but it won't usually harm you or your foetus. But if you experience sudden swelling in your face or extremities, call your doctor or midwife immediately, especially if you also have a severe headache, pain just below your ribs, or vision problems. These can be symptoms of pre-eclampsia , a rare but serious blood pressure condition that needs urgent treatment. Carpal tunnel syndrome. If water retention is causing swelling in your hands and fingers at around 33 weeks pregnant, this can put pressure on the median nerve, which runs through your wrist, causing carpal tunnel syndrome.
The symptoms include pain in the palm of your hand, thumbs and fingers, and sometimes muscle weakness, numbness or pins and needles. Carpal tunnel syndrome will usually go away by itself soon after your baby is born. Until then, you can try and ease the symptoms by cooling your hands with an ice pack. Wearing a wrist splint may help to keep your wrist straight while you're asleep. This can help reduce swelling by improving the circulation in your hand.
If you've got carpal tunnel syndrome, ask your midwife or doctor about other ways of easing the symptoms. Itchy skin. Share this post:. Share on facebook Facebook. Share on twitter Twitter.
