Need advice!

Hey y’all, so I need some advice. I’m 3 weeks late for my period as of today. Since I’ve been even 1 day late I’ve been getting faint lines on every test I take. No matter what brand, no matter what colour, no matter what time of day. I took the tests to the doctor and said I’m getting faint positives in which she stated were negative and told me not to be silly cause I’m not pregnant therefore refused a blood test. So I’m in the process of finding a different doctor.

But basically.

Has anyone ever gotten faint lines the entire time and actually been pregnant? I have a feeling I just am slow at producing the hormone but being 3 weeks late I thought it’d have shown by now.

But if I’m not, why am I getting faint lines? My body shape is changing, I’ve got all the classic symptoms.

I’m worried it’s an ectopic, but I’m not in pain at all and have no bleeding and no discomfort. Confused. :( example of tests below
