Hello doctor. Iam PCOD patient. This is my 3rd IUI. I took fsh 75 injection and hcg trigger shot for mature eggs. I ovulated on day 15. Me and my husband had intercourse on day 12 and day 13. Hcg trigger shot was performed on day 13 night at 7.30pm. On day 14 at 2 pm 1st iui was performed and on day 15 at 2pm 2nd iui was performed. Egg rupture was visible in ultrasound on day 15 morning. My egg size was 19mm on day 14 and endometrial thickness was 11.5mm. My husband had sperm count of 30 million post sperm wash and sperm motility was 5% pre wash and 30% post sperm wash. What are my chances of pregnancy doctor? Iam very tensed since this is 3rd iui. Please give your advice. Iam taking duphaston 10mg tablet from day 17 . Doctor adviced me to take 2 times a day. How long should i take it? And is my pregnancy chances higher this time? When can i take pregnancy test? Please give me some hope doctor
