I don't know about metformin but prenatals won't cause a false line. I don't know how many things can, but as far as I have read it isn't a huge amount of things, fewer that are actually proven to cause false positives (usually some fertility drugs), although there are a few that some say cause false positives but they don't for others, I can't explain that. Bella makes a good point but I don't think what you're taking can cause that, I would have thought you would have always had false positives all the time if that were the case
I been taking it for 3 yrs the metformin it's never gave me false lines
