This type of proble with irregular and excessive bleeding is called as menorrhagia
. Many times it is very difficult to get the perfect reason for this condition. Most of time change in hormone levels is a common cause for abnormal menstrual bleeding
To make the diagnosis for this condition you need to undergo examination and investigations by a gyneacologist. After history, examination and investigations only a cause for this problem can be confirmed.
The drug Femilon
which is being prescibed to you right now is mainly a oral contraceptive
pill and it helps in maintaining the hormonal
balance which is involved in menses. So this drug can be help ful in this condition of yours. As far as the side effects are there, they are very safe drugs and as you know that OCP can be taken for long time without any side effects. But there should not be any contraindication for the used of OCP with you.
I would suggest you to keep in touch with your doctor after starting this medication and if there is any problem because of this medication, you should tell this to your doctor.
Thanks and take care.
