Chemical pregnancy?

Ca

I’m only 3 weeks 6 days today. My strips had been getting darker (but never got very dark) and today they are vvvvfl. I think I’m having a chemical. Going to the doctor today even though I know it’s just going to be a blood test. I haven’t even missed my period yet but I had been getting positives the last 5 days. I know it’s so early but I’m still upset.
