<s>[INST] I am 26yo and 10 weeks pregnant and my last 2 bowel movements have been very light tan color. I haven t changed my diet but have been nauseous the last 6 weeks. My back was hurting just below my ribs on the right side so I went in and was told my urine is normal. I am otherwise healthy. [/INST] Hello and Welcome to ‘Ask A Doctor’ service.I have reviewed your query and here is my advice.It is nonspecific. The tan color could be due to the diet taken and if you do not have any symptoms like pain, fever, and nausea, then it is nothing to worry.For back pain, take care of good posture while sitting and sleeping.Hope I have answered your query. Let me know if I can assist you further. </s>
