As any woman with infertility, I’m learning a lot more about pregnancy and getting pregnant than most people would know in their lifetimes, unless they happen to be gynecologists or reproductive endocrinologists.

I’ve learned in order to ovulate you need follicles large enough to release an egg each month. The ideal follicule size for the “leading follicle” is 23 to 28mm, and you should have one follicle at least 18mm before “triggering” (i.e. stabbing yourself in the stomach/butt with HCG to induce ovulation) — although according to the internet some fertility specialists say the follicle just needs to be 14mm before triggering and you can still get pregnant. Mostly I’m reading it’s 18mm minimum, so I’m not that far off…

I was told by a fertility nurse that follicles should grow at about 2mm per day. At my CD9 appointment, I had 14mm and 9mm follicles on the right and 12mm on the left, so that sounds good, I think? I’ll be going in for my next ultrasound on Sunday, so if the 2mm a day growth projection is right I should have 20mm, 14mm and 18mm follicles ready to go. I’m not sure exactly when they stop growing, but that seems promising.
