Trying to get pregnant. On 17th of this month my follicle size is 21 mm & other 17 mm. I got an injection to rupture the egg at 6 pm on the same day. We had intercourse on that night. On 18th morning 10-11 am I got ovulation pains. No intercourse on that day as suggested by Dr. On 19th I had iui at 11 am and after few min I underwent scan which showed one ruptured follicle & 17 mm follicle. Please let me know if this timing is correct for iui? What are the chances of conceiving? What is the best time for iui? Before ovulation or after ovulation? Will my 17 mm follicle wil also gets ruptured?
