Ttc for 15 mnths

So myself and my partner have been ttc for 15 months now, with no luck at all.. my doctor has told me im not ovulating which has resulted in me having a number of appts with gyne in my local hospital!ive had all the tests needed done and all results are normal!! They have told me when i return on the 23rd of this month they may introduce medication to help me ovulate. Has anyone else had this bother?? Im slowly losing hope and feeling depressed..
