Even more confused

If you read previsous post, I took a test on December 1st. That test had a very dain pink second line. Long story short I was testing every few days, for weeks, trying to get a darker line and the results were literally all over the place. Some days were stark negative, while others had the same very faint line. I came to the conclusion that I must be having a chemical pregnancy and I stopped testing and was waiting for aunt flo. Today, since still no aunt flo, I decided to take another test, and this is what I got.... so confused as to what has been happening. Also I know I need to get in to see my doctor, I'm just waiting for issues with my insurance to get cleared up. Another note, I was NEVER able to get a second line with FMU it is always afternoon when I get positives... weird.
