Yes I advise that you get this checked before October.. that is too long to wait for this in my opinion...
It can be different possible causes...
Post-menopausal bleeding is the medical term..
The main potential worry would be to rule out endometrial cancer...
So you should have a pelvic exam/ pelvic ultrasound / Pap smear and endometrial biopsy most likley
The problem may occur for different reasons..
It is often associated with HRT ( hormone replacement therapy)
ulcers of the vagina or cervix could cause..
It is helpful to get a pelvic ultrasound to evaluate the appearance of the uterus and the endometrium within it...
I hope that this information is helpful for you.
Let me know if you have further questions.
I will be happy to get back with you.
If my answer has been helpful and to your satisfaction then please remember to leave positive feedback.
Thank You and Best Regards,
