Hi thanks for your question.
Vaginal discharge during pregnancy
is normal and is due to various hormonal
changes which occur during pregnancy,
But green vaginal discharge
along with itching indicates fungal infection
You vaginal swab also indicates same finding.
You have candidasis, which is a fungal infection caused by fungus called as candida.
Yeast is also fungus.
The other cells which are mentioned in report are due to same infection.
As gram stain is negative you don't have any bacterial infection.
Hope I answered your question
