Please help with confusing tests. 😑 *update*

Background- I have five healthy kids. I lost my daughter Hannah to a placental abruption at 22 weeks in June.

Since then I had three chemical pregnancies in a row. I was catching the egg every month but it wasn’t implanting. I have been doing baby aspirin, pineapple core, zinc, supplements up the wazoo.

Three days ago I got a faint positive on a Walmart cheapie

and became hopeful and excited.

Since then I have taken tests, different brands, every day.

The Walmart ones got darker.

The blue dye cheap ones are positive.

The internet cheapies are positive.

I have never gotten a positive FRER.

And this morning at 12dpo:

Here are the first responses:

I am terrified that I’ll have my fourth chemical in a row. Not getting positives on the first responses feel like a death knell.

Does anyone have any encouragement or stories about what could be happening here?
