Hi, thanks for using healthcare magic
Delayed periods can occur for a number of reasons including : (1) hormonal issues such as abnormal levels of hormones such as thyroid hormone or prolactin (2) inadequate diet (3) stress either emotional or physical (4) excess physical activity (5) PCOS which stands for polycystic ovarian snydrome- this consists of irregular periods
, polycystic ovaries
on ultrasound, insulin resistance
, hair growth in places abnormal for a woman such as chin, chest , abdomen
Technically infertility is not diagnosed till a yr of trying to conceive, but you can consider visiting your doctor for an assessment to determine if any of the above is affecting your period. You will be required to do some blood tests to check hormonal levels.
Treatment is available to regularise the periods and allow for contraception
I hope this helps
