Ovulation already? Help!

Ally • Married 💍 Mother of one.

From previous opk I’ve done seems like my highest days are Cycle Day 16 or Cycle Day 18. The one on the top is from yesterday evening, 4/11/18 Cycle Day 17. Seems like it’s close or at the peak. The one the bottom is from this morning, doesn’t seem as dark, Cycle Day 18. What do you ladies think? Have I ovulated or am I close?
