Brief Answer:
Can be due to vaginal atrophy or endometrial cause.

Detailed Answer:
Hello,
Thanks for posting your query.
Post menopausal bleeding is a common problem however the most common cause is a problem with the endometrial lining of the uterus. The other causes can be divided into gyneacological and non gynaecological. The most common gynaecological causes would be vaginal atrophy or dryness or problems related to the cervix.
The vaginal dryness would respond to topical estrogen replacement creams and a pap smear would be able to assess the state of the cervix to determine if there are any problems with it.
Lesions of the ovary can also cause this symptom
1. You need a visit with your OB/GYN and an exam
2. During this exam they need to perform an endometrial biopsy
3. You then need an ultrasound to look at the ovaries and the endometrial lining

If the biopsy is normal and the 'lining' of the uterus is 4mm or less, then there is absolutely no need to worry.

I hope this answers your query.

Brief Answer:
Better to arrange an early appointment.

Detailed Answer:
Hello.
Thanks for writing again.
One month is a too long time for the bleeding to persist. It is better to arrange for an early appointment.
The nausea and abdominal pain are not likely to be related to it. This can happen due to gastric issues or indigestion. You can take medicines like omeprazole and domperidone and see if it helps.
Hope my answer is helpful.
Do accept my answer in case there are no further queries.
Regards.
