Is this dark LH for 4 days DPO

Did you confirm ovulation? Like with BBT? Your body could be trying to ovulate now if it didn’t 4 days ago. Sometimes it’ll try and fail, so it tries again in a few days. I once had 4 LH peaks in a cycle. The last and strongest peak is true peak.

I have been pregnant three times and tracked LH with all pregnancies (I’ve also had 2 miscarriages and tracked LH/HCG down. And I’ve done 4 trigger shots with IUIs and tracked LH/HCG down).

LH does pick up HCG and will get darker if you’re pregnant. But if you’re truly only 4dpo, it wouldn’t be dark because you’re pregnant. The egg hasn’t even implanted yet to start producing HCG.

Lh does have natural variations. It’s not always linear up and down. So it could just be normal shifts and changes.

I’m not familiar with these tests, I’ve used Inito and Mira and especially the first 1-2 months after a miscarriage were very erratic and it seemed like I had multiple ovulation attempts. And the last time I got pregnant my LH was very low at 0.8 at 4dpo, but by 18dpo it was maxed out. Usually the implantation happens much later, so I don’t think that your LH rise is an indication of pregnancy - unless you ovulated a bit earlier than you thought?
