How big were your follicle(s) at time of trigger?

Hey so i triggered Sunday the 28th for my IUI and I only had a 17mm dominant follicle 😔 I was very concerned about it not being at least a 18mm. My estrogen was 295 with that 17mm follicle and my lh was 10.97.. given that my estrogen was high it kind of makes me feel better about this cycle but last cycle I had a whopping 23mm follicle triggered and did TI but it ended with a BFN. I just had my IUI yesterday at 10am and I had mild cramping from the procedure but the cramps went away. Just curious to know what size were you ladies follicles and did the cycle end with a bfp or bfn
