Q. Is this an infection or pregnancy? I am worried with the white odorless mucus discharge. My hubby and I are also trying for baby. I have browsed the web and found that this could be possible infection also. Is this an infection or pregnancy?

A. It’s a cervical discharge and mucus secreted may be majorly a sign of pregnancy. I too had the same symptom but was tested positive for pregnancy. At times it may be a normal vaginal discharge. Generally it will be a yeast infection. Just check for your body temperature changes as it indicates good for you. Your mucus will be like raw egg white, the more thick more chances for positive. Keep a check on these factors. I shall suggest you to visit the doctor to confirm the same instead of making your own conclusions.

Q. What are the symptoms of salmonella infection?

A. Dehydration is the principal clinical concern. The incubation period – the time between ingestion of Salmonella bacteria and the onset of illness – varies from six to 72 hours.Salmonella can cause three different kinds of illness: gastroenteritis, typhoid fever, and bacteremia.Symptoms of Salmonella gastroenteritis include diarrhea, abdominal cramps, fever, nausea, and/or vomiting.In mild cases diarrhea may be non-bloody, occur several times per day, and not be very voluminous; in severe cases it may be frequent, bloody and/or mucoid, and of high volume. Fever generally occurs in the 100°F to 102°F (38°C to 39°C) range. Vomiting is less common than diarrhea. Headaches, myalgias (muscle pain), and arthralgias (joint pain) are often reported as well.Whereas the diarrhea typically lasts 24 to 72 hours, patients often report fatigue and other nonspecific symptoms lasting 7 days or longer.
