Opks- HELP!

Mary Beth
Okay so I'm getting extremely frustrated, these are supposed to help reduce our stress not make it worse! I've been using clear blue digital advanced and I get
 errors all the time. I don't understand why and I use them the exact same way everyday, sometimes they are errors and sometimes they work which makes no sense. Any one else have this happen? Anyway, I got two errors this morning and then used a test strip. Here are my results, opinions?!? I never seem to get one darker than this.
