1st response vs ultra early 10m cheapy-which is most sensitive?

[broodywantcoilout]

as the title says. if an amazon cheapy says faint positive today, how long before it might show up on a first response?or do they have the same sensitivity

I did exactly this with my last pregnancy (unfortunately mc'ed at 7 weeks but still). Did a 10ml cheapy at 9dpo, neg; 11 dpo, neg; 14 dpo v faint positive. Did a FR with same sample and was really clear positive.

FR are meant to be less sensitive but I think they have more of the reactant and therefore show a clearer line IYSWIM.

Do you have a faint pos? What dpo are you? I'd get yourself down Tesco's and test with some nice strong morning pee first thing tomorrow. Good luck!
