I went through the same thing and i was told that a pregnancy test will not say pregnant unless it detects that hormone that says you are. some tests are more sensitive to that hormone than others to. so i would take another test and see what that says.
the sensivity level on that one is 40 or 50...so if you got a pos on it you should have a good bit of hcg in your system. Do you know what the sensivity level is in the other ones you took? Try to take a dollar store one from dollar general...they pick up 25 mui or miu which ever it is.
I would wait and retest in 3 days with first morning urine.
clear blue easy digital (thats the first one that was positive for my first child)
Retest in three days. Then see your doc.
usually the digital test are not as strong as the others....what brands did you use?
I should be due to get my period again in 3 days
It could be the positive test was more sensitive to picking up the hormone and that's why it was positive. When were you due or are due for your period? I would try first morning urine. But, to ease your mind, you may want to go to the doctor and get a blood test.
