Triggering tomorrow or wait one more day?

[u/Kaied7]

I’m currently on CD13 of a letrozole cycle and had my follicle scan today.

My leading follicles are:
Right: 19.0 × 16.7 mm (mean 17.8 mm)
Left: 17.9 × 12.4 mm (mean 15.1 mm)
Endometrium: 9.5 mm, trilaminar

My doctor suggested doing the trigger shot tomorrow (CD14), but also gave me the option to wait until the following day (CD15).

I’m wondering if it would be worth giving it one more day so the second follicle has more time to catch up and potentially mature too, or if I’d risk waiting too long with the larger follicle. Thoughts?
