I am married for 5 years. Have hypothyroidism since 2006 (taking thyronorm 62.5), pcod and block in right fallopian tube. Have been taking ovulation induction medicine s for past 2 cycles. This cycle took letrozole 2 .5 mg twice a day (from day 2 to day 6) and persinal 75iu on 3,4,5, the day. My egg size on the right side measured 1.8x1.9 on 8th day. Hence doctor gave me hcg 5000 injection for egg rupture. Checked on 10th day today. Egg has not ruptured yet. Egg size has grown to 2.0 x2. 1 and endometrium is 9 mm. Why my egg did not get ruptured? Doctor asking me to check again on monday the 12th day. Should I have to put another injection?
