This cycle i was on clomid for cycle day 3-7. Had four mature follices when I received hcg injection on 18th April. Confirmed ovulation by tvs on 22nd april. Was advised to take estradiol tablets and progesterone vaginal gel. On 8th may, had mild brown discharge. On 9th may, had brown clots but no proper blood flow. Urine Pregnancy test is negative on 10th may. I am not sure why blood clots were formed and passed. Never had this before during my periods.
