What Causes White Vaginal Discharge While On Clomid?

Hello Doctor. I have pcos and thyroid. Me and my husband have been trying for a baby for four years plus. Dr did an ultra sound and confirmed that I was not ovulating. He put me on clomid and in my second cycle of clomid, on day 12 during ultra sound, dr said I had an egg in my fallopian tube about 21.7 mm and asked me to get together with hubby on day 14 night. We followed the drs advice and we also did on day 15 night as well. Post which till date we haven t got involved. Today I m on cycle 22... From cycle day 14 till date I have been having milky white discharge. I would like to know the reason as I had never experienced continuous vaginal discharge like this. Usually it occurs to me after my period or before my period. Kindly help me
