Had my first IUI (natural) yesterday. Based on 8 months or so of BBT and OPK charting, I believe I typically ovulate early--day 12 or 13. Yesterday was day 12. On day 11, I got a positive opk around 11:30 a.m. Still positive day 12. Went in day 12 and the ultrasound showed a 17 mm follicle at around 1:30 (26 hours after first positive opk. The NP advised maybe waiting another day but left it up to me. She ultimately said it was fine to go ahead since the sperm can live a few days in the uterus. My temp rose half a degree this morning (day 13) and the opk was negative this morning.
Was my timing right? The temps/opks seem to say so but I'm unnerved by the follicle only being 17 mm. What do you all think?
