My age is 25. Got marriage 3 years ago. Trying for kids. Recently, i am taking ovulation induction fertility treatment. At 17th day (Dec 17) of my cycle follicle size is 19 mm and et is 9 mm. My doctor gave hcg injection on Dec 17 (17th day of cycle). Again I taken scan After 48 hours after Hcg trigger shot (Dec 19). And my follicular was ruptured. I had intercourse on and after hcg shot (i.e., on Day 17, 18, 19, 20). Specifically, i had intercourse 2 times a day after hcg shot. Now 24 hours is over after egg rupture. Still how many days i need to intercourse. Please suggest I heard that egg will live about 24 hours.
