Very dark and yellow urine with pungent

Since you are drinking plenty of water, your urine shouldn't be in dark yellow color. I assume you don't have abdomen pain or burning sensation when you urine as this may be due to urinary tract infection. The color and smell could be due to excess vitamin. Try only consume supplements prescribed by your gynaecologist. The condition should improve. If it doesn't, please consult your gynaecologist. Take care.
