well it could still be too early to test :) im hoping you get your BFP this month and i personally dont like the dollar tests i got a faint false positive with them a few months back soo i dont rely on them.at all even tho i love the price sending you lots of SSBD
I did read somewhere that DG test levels are 50. So, that made me feel better. But, I was told by RE that it took 13-14 days for the HCG trigger shot to leave my system, so I was expecting a BFP from that at least. I guess the good thing about that is when I test again I won't have the "what ifs" with the shot being in my system since I'm already getting a BFN.
I used a DG test 2 days before af and got my bfp with this pg, so i think they are pretty accurate. Remember everybody is different too. LOTS OF BABY DUST!!!!!!!
Im not sure the level is but that is how i found out i was preggers with my first. so it is pretty accurate.
