Can taking the hcg trigger shot after ovulation cause problems for eggs or fertilization? I took gonal-f and triggered on cycle day 12 (timed intercourse). I had ewcm on day 11 and 12 (before the trigger), and haven't had any since. My cd10 ultrasound showed 3 follicles at 14.5, 15.5, and 16.5. Do you think it's possible that I ovulated before the trigger? Last month my ewcm started the day after trigger.
