5 hari opk positif

Aih sabar ye, I know how stressful this is! OPK positif for 5 days is actually quite long, mine was usually just 1-2 days, so it's possible your surge was extended, but the UPT negative with 11 days delay is confusing, I get it. A few of us mums went through something similar and it turned out to be hormonal issues or the OPK was detecting something else, so I really think you should see your doc to check your hormone levels and rule things out, at least you'll know what's going on instead of stressing yourself. Fingers crossed for you, but don't rely on just the tests lah, the doctor can do proper blood work to confirm.
