Does anyone know how to read the clearblue easy fertility monitor stick manually?

My doc said on Sunday that i should ovulate either Monday or Tuesday based on my sonogram. Monday was a bust. I did not ovulate though it looked like I was gearing up for it. Well then today I peed on the sticks this morning and my monitor just said high (it always says that since I have PCOS) as usual. The second test that you read manually that I bought to back up my monitor looked like it could be positive either way. Both lines were even and it was too close to call. Well my doc told me to test twice a day with un-concentrated urine. So I just drank 3 glasses of water and went to test again a second ago. The one i read manually is full on positive. No doubt about it.The one I used for my monitor has two bold lines. The line near the pee wick is slightly darker but they are both dark. I have NEVER had two dark lines like this and I have never ovulated before (first time on clomid) Do you know if that means positive? I made an appointment this morning for another sonogram and a LH test tomorrow morning since I hadn't tested positive yet for ovulation. Should I just go or should I call them before hand telling them I think I might be ovulating? Its important cuz I am getting an IUI. I dunno what to do. Since I have PCOS I noticed if I tested in the afternoon with concentrated urine it would ALWAYS be positive no matter what day it was. My pee didnt seem extra concentrated but now I am still unsure if my PCOS is getting in the way!
