All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.

Sister, may you have a happy and blessed Ramadan! Thank you for your question, which indicates your eagerness to live according to the rules of Islam. You are right to turn to knowledgeable people, rather than to friends or relatives, for answers to such questions. May Allah Almighty help us all adhere to the principles of this true religion, Islam, and enable us to be among the dwellers of Paradise in the hereafter. Ameen.

As regards your question, we would like to make it clear that a gynecological exam during the days of Ramadan is not among things that nullify fasting. So do not worry about your fasting and go ahead with your docotr's appointment.

In his response to your question, Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states the following:

I commend you for your zeal to know the rules of your religion. I pray that Allah grant us all beneficial knowledge, humble hearts, and acceptable deeds. Ameen.

Coming to the question you have raised, let me state the following:

The gynecological exam you need to undergo for medical reasons will not nullify your fast, for it does not fall in the category of things that invalidate the fast. Fasting is obviously nullified by deliberate consumption, intake, or ingestion of food, nutrients, or drinks; sexual intercourse; induction of emission of semen [or, in the case of women, sexual secretions] through masturbation or other activities; induction of vomiting; cupping; onset of menses or bleeding of childbirth; or deliberate intention to break the fast.

The exam you have mentioned does not fall in any of the above categories.  So you need not worry about going ahead with the exam.

May Allah accept our fasts and make us all worthy of meeting Him on the Day of Resurrection. Ameen.
