So ladies I normally use opks but this time I tried the expense ones. I normally get a pos opk around cd 17. Today is CD12 & I received a peak smiley. I have been using FMU like the instructions say. I also had intercourse last night.

Would that mess things up? I’m going to test again a little later to see if it’s still a peak.

It was low cd 10

High cycle day 11

Now peak cd 12
