Chemical but positive test or not chemical

Guys I need advice and help. My doctors have been no help what so ever. My doctor said blood is going up how he expects it to.

Yet I started bleeding. Not colts or anything just regular bleeding yesterday around 10 am

So it’s been 24 hours now

My test are positive and darker

Is this a chemical? I’m so confused

Tuesday or so

Thursday night

Friday morning

Please help

I’m confused and emotionally distraught

I thought we were miscarrying yesterday...
