Thanks for writing to us with your health concern.
Yellowish urine does not indicate anything much.
It could be dehydration
or a UTI if accompanied by itching, burning etc.
In absence of that, it just means you are not drinking enough water.
Pre menstrual spotting can be due to lots of reasons - stress, anxiety
, weight gain etc.Endometrial hyperplasia
, fibroid, PCOD need to be ruled out.
Please get yourself investigated thoroughly for infertility
