Are Amazon Cheapies not as sensitive as they used to be?

Got very early results with my first two with Amazon Cheapies and everyone swore by them. I've seen a few comments recently that lots think they are less sensitive than 25 miu tests now, and speculation that they aren't really 10miu anymore. Does anyone have experience with this? I'm feeling down as 10/11dpo and bfn's on Cheapies today so maybe just looking for false hope!

Mine were advertised as 10miu ones, and ingit my bfp the day before my period was due. The dating scan then put my due date back by five days. So it must have detected it pretty early!

But don't go mad! Try not to test so often if you can stand it.
