I have had a very unusual cycle this month. Im 4 days late but had a veryyy late positive opk so I think things are whacky but in any case, the other day I took an opk and hcg test together and put them next to each other, touching, to see if I could at least look for where a positive line would show up on hcg

. and voila! a positive hcg showed up. skeptical, I tried the same thing with two hcg and again, positive. But all tests since, including a frer with fmu were negative. BE CAREFUL!!! certainly gives false hope.
