How many mature follies did you have, and what size were they when you triggered?

I only had one and it was 14.5 at 11 am Friday, and I triggered Sunday 9 pm for a Tuesday 9 am insem. So I'm guessing that 2.5 days meant it was around 19 when I triggered? Just before the trigger, my OPK was still very clearly negative, so I think my poor follie was too small/immature as my body wasn't getting ready to release it.
