FET: Very faint line on test on official test day

[BeaCat]

Hello, I had an FET 13 days ago with 5 day blast. I've been really patient and not tested until this morning where I got a very faint line on the test. So now I feel confused. Do you think it could be a chemical pregnancy and now it's gone away? By day 13 I'm guessing it should be a strong line so not feeling hopeful. Anyone else had this with a positive outcome?

@BeaCat I've never had any experiences with bfp to know, but from what I've read with others, some don't get a strong line until a few days after their missed period x

It must be a good sign, surely! Have you tried one of the digital tests? X

@kelly199 @Fingersxssd83 thanks for your replies. I think the test the clinic gave me must not have been the best as I went out and bought a First Response and got a very clear BFP! Yay! X

@BeaCat only just seen this, sorry!! Big congratulations!! Wish you a healthy and happy pregnancy! X
