Hi doctor. My query is- I am having pcos and thyroid. Last cycle I took clomifene citrate and hmg on cd-3 & 5. I ovulated on day 11. I was 17 days past ovulation and my af was due today. I was about to take home pregnancy test but noticed my af has started as per its right time. Why so? I took treatment and ovulated also but still no results for assisted pregnancy? I was hoping for pregnancy but this is heart breaking. I had a still birth 9months ago. For that also I took treatment they make me ovulate through hmg and then trigger hcg for rupture. And I conceived in first time. Taking same treatment this time but cycle failed why?
