Hi thanks for your question
Your 6 weeks pregnant and having vaginal discharge
,changing colour from pinkish to milky.
You have history of two miscarriages and you have taken Inj HCG 1000 i/u.
The vaginal discharge during pregnancy
is normal thing,
It is due to various hormonal
changes during pregnancy,
The inj HCG is given to you to prevent any miscarriage this time, as HCG deficiency
is a known cause for miscarriage.
Hope I answered your question
