Are they getting darker?

I took the first test Saturday and the last test this morning, are they getting darker? According to my app I’m around 4 weeks and 4 days so I would’ve assumed they’d be darker. I’m thinking of maybe trying some different brands and see what the outcome is or maybe try and book in some bloods with the gp.

I wasn’t having regular periods I never have after the depo so honestly I’ve no idea how far along I could be especially as we didn’t dtd on ovulation or what should’ve been my ovulation period.
