Had anyone had a negative/very faint positive with sainsburys test and then gone on to test positive on other branded tests? I did a sainsburys one this morning (I'm 3days late) it was more or less negative, or a very faint like if anything in the light, I don't trust it after reading the reviews. But I feel so pregnant! 😔 maybe I've got it wrong and AF is gonna arrive.. isit worth trying a different test?
