False positive?

Samantha

So over the past 2 days i have taken a total of 7 pregnancy tests, 5 of which i have taken today.

Well i ended up at the ER and it took them 2.5 hrs just to bring me the results of my urine test to which they say is negative.... i get home at 7p.m and take another test and its a big fat positive.... i have no idea what to do... anyone ever have this happen?
