Giving me slight hope

I started testing at 9dpo which were negative

10dpo vvfl

11dpo vvfl but slightly more pronounced then 10dpo

Today - 12dpo 2am vvfl but 9am negative

That made me concerned possibly a chemical pregnancy but... I found this article about how dehydration can cause hcg levels to stop rising or dip

Yesterday I was outside for 6hrs in the hot sun. I know I became very dehydrated but couldn't keep up water intake.

I'm trying to rehydrate myself today and hopefully my levels start rising again and my line returns 🙏 hopefully I didn't cause any damage
