Thanks for your question on Healthcare Magic.
I can understand your concern.
You are having menstrual irregularities.
And most common cause for this is
hormonal imbalance.
Staying awake late night can cause
stress and
anxiety. And this can cause hormonal imbalance and menstrual irregularities.
This menstrual irregularities can further increase chances of
infertility.
So staying awake late night can indirectly cause infertility.
So better to consult gynecologist and get done hormone levels to rule out hormonal imbalance as a cause for your irregular menses.
Sleep on time and avoid late night awakening.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
