Hello, thanks for using health care magic.
Feeling of cold, shivering and abdominal cramps do not appear as normal symptoms especially for pregnant women. The most likely causes could be an infection and includes an enteric fever
or malaria and a urinary tract infection
should be ruled out.
It is better to consult with a gyns/obsts for an evaluation and for tests such as stool, urinalysis
, widal serology and complete blood count
in a bit to understand what could be the cause of the symptoms.
Best regards and hope this helps.
