So if I took a test at 830 this morning and got a faint line then I peed two more times after that catching the third sample in a cup about 1130 ( I haven't drank anything in between ) I took the second test and not sure I see anything. ..I'm only 9 dpo af due in 6 days.. I used first response for both...but my question is ...could I not have enough hcg by the third sample?
