Just to bring a downer into this thread, i got a bfn this morning, used a diff brand though so maybe still too early,
I had bought one of the higher rated brands and we pulled 2 or 3 BFP's but then DW (the test junkie) went out and bought a generic set of three. Two showed up negative and one was defective. So we went back out, bought the good brand again and have since used another 3 or 4 and all say BFP. Plus we now are starting to get other symptoms so I think we are good. I would recommend getting the better brand to see.
