Hello,
Thanks for writing to DoctorSpring.com with your health concern.

Could you please upload the ultrasound scan or the reports which have diagnosed these multiple lumps ?
Also, are you sure there is no spelling error in the query ?
' Llangefni ' lumps are unheard of.

You should definitely investigate irregular cycles, particularly the episode of bleeding constantly for 10 weeks, even if it is only spotting.
The possibilities could be PCOS - polycystic ovarian syndrome.

In this condition, the ovary is studded with multiple small cysts, none of them mature to form a follicle which ovulates, hence cycles are irregular and ovulation is unpredictable.

Also, endometrial hyperplasia ( thickening of the lining of the uterus ) leads to irregular cycles, with prolonged spotting, as the lining takes a long time to completely shed off.

Hypothyroidism or prolactin level alterations can lead to irregular cycles.
Ovarian cysts could be responsible, or there could be a polyp in the cervix or protruding from the uterus.

Sometimes, stress, tensions, weight gain, ingestion of medications that affect the hormonal axis, changes in diet or sleep patterns - these could be responsible, but since your irregular cycles are chronic, I think there is a basic underlying disorder.

You should consult a Gynecologist and have -
1. Internal check up - per vaginum and per speculum
2. Hormonal measurements - FSH, LH, TSH, Prolactin, OGTT, Lipid profile, DHEAS, free testosterone, fasting insulin
3. Pelvic ultrasound scan.
This much of a workup will definitely reveal the condition.

All the best.
Please feel free to ask for further clarifications.
