I use First Response (pink box). Keep in mind that if it's not lighting up meaning giving you the two lines you are probably not ovulating. Best Wishes to you!!
I like Clear blue easy digital, you get a smiley face when u ovulate.
I've heard Clear Blue Was Really good. Haven't actually tried it myself... Yet. I took my last dose of clomid today so I'm probably gonna go for that one. Let Me know how it works! =)
