Are cheapies just as good as brand name? I dont know how many dpo i am.. but ive gotten a faint positive on 3 premom test strips on 4/7/24 then i went an bought a first response which was negative. I tested everyday since an all negatives.. tonight 4/11/24 i used 2 clinical guard test strips an they were both faint positives. I dumped that pee out *which i shouldve save*. Got dressed an went to the store. Not even 15 mins. Came back kinda forced myself to get some pee into the cup an took a clear blue test an negative? What are the odds these strips are giving me false positves?
