Clomid

I'm taking Clomid 50 mg. I tested my ovulation on the 16th and got nothing but it wasn't my ovulation time. I tested again on the 19th only expecting peak if anything. I wasn't expecting to see high fertility until tomorrow but the past 3 days the clear blue digital opk has been flashing a smiley face signaling high ovulation. Should I trust it? I'm trying not to get my hopes up... But I really really really want it to be true and me to be pregnant. Lol
