I had an HCG trigger (10,000units) on 10/2. Yesterday when I came home from work (9am--i work at night) i took a HPT and it was negative. no question, absolutely negative. when i woke up this morning i took a test (12 days after HCG trigger) and there was a faint line. DH and a friend both viewed and agreed. i talked to a friend that had an IUI as well and she got her BFP. She suggested taking another test this afternoon without FMU to see if it would be negative like the one from yesterday morning. so, i took another test and again, a positive. the lines are faint, but i can see them from the counter if i stand over them. i dont have to pick them up and inspect them or hold them to the light or turn them upside down (come on--you know you do it too...

).
the problem is: it very well may be HCG trigger left over. the only thing making think otherwise is the negative from yesterday. i will test tomorrow morning. if the line is darker then i will have a better idea if it is the real deal. (fingers crossed!!)
