welcome to hcm,
I really appreciate your concern,
You may consult A/E department for anearly review.
May i Know your age? as,
Risk of uterine malignancy is quite low before the age of 40. However, this pattern of blood loss can leave you anemic. So, evaluation & treatment are necessary.
Most important test you need is a pelvic
ultrasound to see if there is any organic problem.
Yes
kidney pain can be a lower
back pain but it is rarely associated with vaginal bleeding
You surely need a Gynecologist opinion. As your speculum examination by an expert is necessary to exclude any polyp or other obvious pathologies.
It would be unsafe for you to take
hormonal pills without testing. Until your evaluation you may take Mifenamic acid 500 mg TDS, if you have no contraindication. Best is to visit an emergency department for evaluation & to get a prescription.
Please feel free to ask if you have any further questions,
Thanks. Regards.
