Confusing ovulation test result (photo)

[mammaofmany]

This is my first month tracking ovulation and I'm confused about my "peak".
It's saying it was super high on CD 16... but to my eye the line looks much darker today, yet the app is saying it's lower than yesterday. Should I consider CD 16 my peak still?

If its the darkest line going forward you can yes. But do long as you're DTD every other day then you have done your part.

Best time to test LH is your second urination of the day (e g. Between 10am-2pm) to get a more accurate reading.

HCG is the first urine.

By the time you've ovulated it's nearly too late, for the best chance you want to be dtd a day or two before ovulation. So I would probably consider today your ovulation day and if you've had sex in the past day or two you have every chance of conceiving.

17th looks the highest to me. I always trusted my own judgement over the app, different lighting and stuff can throw it off.

Thanks for the advice. LH dropped the next day so I guess it doesn't really matter as I've narrowed it down to a two day window!
