I appreciate your query.
It is unusual for nausea
to persist till the 34th week of pregnancy.
However, I would advise you to consult your doctor, and also get your Liver Function Test done, as sometimes, mild liver derangement in late pregnancy manifests in this way.
It is also possible that you might be having gastritis
( acidity ) which causes indigestion
Try taking small frequent, non spicy , non oily meals.
Do not go hungry for more than 2- 3 hours at a stretch - keep having small snacks like fruit, buttermilk, milk, dry fruits etc.
Also, try crackers or dry toast on empty stomach first thing in the morning before getting up from bed.
You can also try taking antacids and antiemetics ( eg. doxinate
) which are safe in pregnancy.
You can consult your doctor for detailed prescription.
Also, your lack of diet and hydration might be causing the growth impairment in the baby.
It is important to consume enough fluids, in the form of water , juices, soups, milk, buttermilk, coconut water etc.. atleast 3 - 4 litres per day.
The doctor would clinically assess the growth of your baby by abdominal examination.
However, at 34 weeks, you can also go for a detailed ultrasound
as well as Colour Doppler of the fetus ( baby ) which will assure you about the growth and blood supply to the baby.
Hope this helped.
