You are 48/f, c/o nausea worse in early morning, passing clay colored motion and heaviness in pelvis for the last 4 days. You don't have any pain any where. You have missed your periods for almost 20 days. You don't have breast tenderness. You say it is unlikely to be a pregnancy
There are only 2 possibilities.
1) Pregnancy - to be ruled out by doing a pregnancy test.
- with or without jaundice
- doubted by clay colored motion and nausea - For diagnosis you need blood test
including serum bilirubin
direct and indirect, urine analysis including Bile salt and Bile pigment
If Hepatitis and jaundice is confirmed you need further investigations after consulting a medical gastro enterologist and follow his advise.
