Opk question

Lauren • Mommy to Evan Isaac and Alison Rose

I am using the first response and opk and never actually had the LH go high enough to trigger a smiley. That being said the stick was pretty dark 2 days ago and today it's super super super light....does that mean ovulation happened? The surgery immediately goes down after an egg is released right?

I had sex today because I didn't realize I missed the surge time but I'm hoping I still just caught it haha :)
