Line progression

[Lillybet31]

Hello! I need some advice, I’m 9 days post embryo transfer and I think my first response line has faded, but I’ve done a clear blue and that’s strip a strong positive. Has anyone had a lighter first response and then it got darker again? Bottom is today, top is yesterday.

HCG doubles every 48 hours so I’m not surprised the tests from yesterday and today look like that; also I don’t think today’s really looks much lighter by the way they look pretty much the same to me. Remember the line darkness can vary with urine concentration too, ie whether you’re more or
less hydrated. Congratulations and best of luck 💘
