When the follicle grows to about 2.0, the follicle development is normal and the morphology is acceptable, ovulation can be induced by breaking the egg injection. The eggs can survive for 1-2 days and the sperm can survive in the body for 2-3 days. If you have intercourse one day before and one day after ovulation, you will have the best chance to conceive, and you can have intercourse on the same day after the egg-breaking injection to increase the chance of pregnancy, so you don’t have to wait until after ovulation. You can use ovulation test strips to detect ovulation. If you have not yet ovulated, you can take a second injection to promote follicle discharge and continue to have intercourse for a few days. If you want to confirm your pregnancy afterwards, you can go to the hospital after 10 days to have a blood test for human chorionic gonadotropin, or you can use an early pregnancy test after 2 weeks.
