I googled. I saw this and it made me happy because yes, this is me!!! Always a line of some sort, not even really "faint." Then bummed because I already opened/used a new pack of OPKs. Chat Icon


Q: How come I always have a faint line in the test result window? Does this indicate a problem?

A: We always have LH in our systems, so the test can pick it up. Most of the tests don't show a full positive result until 25-40 mIU, but many will show a faint line with LH levels over 10 mIU. If your result line often has significant color, you should consider trying another brand. If you still get a significant line, you should consider having your doctor test your LH levels on the third day of your next cycle to see if your hormone levels are elevated. FSH levels should be checked at the same time as LH, especially if PCOS is suspected.
