Can't tell if + or -


Hi, I recently joined this app because my husband and I are ttc. I started using these ovulation strips from Amazon and have been getting a "No LH surge" result, but this one is a little confusing. I can't tell if it's LH surge or not because the control line looks a little more faint this time, not as dark as it usually has been the past few days. Can anyone tell? thanks :)
