Thanks for the query.
Yes, this could be due to pre-meopause. During this period the menstrual cycle can undergo changes due to hormonal
But if there is any possibility of pregnancy
, it should be excluded first.
After that you can just observe your cycles, usually they will continue like this for few months and will stop.
If you are having any associated symptoms like sweating, joint pains
etc. you can take symptomatic treatment.
