I got my bfp a few days ago at 13dpo. Currently 18dpo and the line is darker than 13dpo but the same as 16dpo. Has it reached saturation or should it still be getting darker? I am new to this so unsure what I should expect. Most recent tests shown below - right hand one is today, hard to read because of the dye stealing but the darkest parts on each test look the same. Not sure if they should be getting darker and epu haven’t called me back
