Thoughts on Digital OPK?

I've been getting the blinking smiley face for past 3 days on the Clearblue Digital OPK, today I got the solid smiley face, which I thought meant peak ovulation? I went ahead & tested with First Response OPK and the test line is super faint.. what gives? Which should I go by? Super confusing!!!

Used same urine sample for both tests FYI (:
