Opk tests.

Hey all! This is my first month of fully tracking on my TTC journey. I have been using the app to track my period and then all my data was lost.

Last week on 10/13/2015 I took an ovulation test. It showed an LH surge. Did what we had to do on our end. Well yesterday, I noticed I was overly emotional. Crying over reality television, slight food aversion. Just blah. Was checking my cervix today and it was open, high and medium. I took another ovulation test and got a VERY dark test line.

Would I chalk the first one up as a misread and follow this one?

I'm not too familiar with my cycle as it just got back to a normal 29 dayer recently.

Why would I have two positive ovulation tests SO far apart? Help???
