Don't worry unnecessarily. My Mum used to say "don't waste a good worry" and she was right. Firstly, you chart is very promising and your temps look good (in my humble opinion as I'm not an expert, but getting to be one). Secondly and most importantly, you are testing very early. You are only 9DPO and if you read the advice on FF, it recommends NOT testing too early and shattering your hopes. It is very common to have one or even possibly two dropped temps during the LP and can sometimes be indicative of implantation .... so that's food for thought. I reckon you could test every day if you wished with cheapies (not to waste good money) and if you get a sniff of a test line go for it THEN with an expensive digi.
Lots of people post that they get early positive PG results, but the statistics show that this is a very low percentage of women. You would be a very lucky bunny indeed to be one of these elite few. Hang in there, things are looking bright still.
