Yesterday i went in for an u/s and my lead follicle was around 18mm. I got a negative OPK last night and a negative this morning (Im testing twice a day to make sure I catch my LH surge). Im wondering what the follicle size normally is at the LH surge or right before ovulation? I would assume i will get a pos OPK tonight or tomorrow as I believe the follicle is growing about 2mm a day since it was 14mm on Monday and then the 18mm on Wed. I also can sense the O is coming due to CM increase (sorry if TMI)
I am doing a natural FET by the way and am nervous about not catching the surge or something going wrong. Do OPK's gradually get darker before you got the actual positive?

i used digital OPKs b/c i was so afraid about missing the surge- regular ones are so difficult to read.
i forget what my follie size was when i got pg with Griffin... but with the twins, the morning after my positive OPK my follies were 21mm and 25mm.... 18mm being what my RE considers mature.
