welcome to healthcare magic
from the symptoms you have just mentioned you need to get your blood pressure checked up as you might be having symptoms that are due to high blood pressure
like headache blurring of vision. in medical terms we call it pre eclampsia
i would like to rule out an infection as mostly urine due to the sweating and lower abdominal pains.
would suggest get reviewed by your obstretician and be given appropriate treatment.
hope to have answered your query
take care and all the best.
