HI, thanks for using healthcare magic
Irregular periods can be due to: (!) abnormal levels of thyroid hormone- your doctor may want to make sure that your levels of
hormone replacement is adequate
(2)emotional or physical stress or illness
(3)inadequate diet
(4)polycystic ovarian syndrome
(5) high
prolactin levels- this is a hormone released in the brain
You may want to consider visiting your doctor for an assessment which would include blood tests and imaging of the pelvis.
In terms of the
frequent urination and
flatulence , this may not be related to the irregular period or each other.
Excess flatulence is often related to intolerance to certain foods or excess use of gas producing foods such as beans, broccoli, cabbage, turnips, brussel sprouts, carbonated drinks.
There are different causes of increased urinary frequency, your doctor may suggest a 1 to 3 day urinary diary to identify how much you are drinking , how often you use the bathroom and the amount of urine.
I hope this helps
