Follicle sizes in ovulation induction

Lasagneismyfave2024 profile image

Hi, I was just wondering for those who went through ovulation induction, how long did it take for follicle size to reach 18mm? I’m currently day 13 and follicles are 11.5mm, so I’m just wondering what everyone else’s experiences were?

Thanks.

Every thing seems on track - good size follicles for Day 13 You should see a difference with your next scan - they can grow 1 to 2 mm/day

Good luck with your treatment

Hi I had a dominant follicle on day 13 that measured 18mm and had a trigger shot on day 14. Everyone’s experiences are very different. I know there are some people who got their dominant follicle around day 18/19. My nurse told me anything over 14mm is capable of ovulation so those 11.5s can grow. Keep us posted with how you get on and good luck x
