I am definitely going fpr a positive!!! I had the same as you 10dpo and I didn't get too excited either as I wanted a big line and then as the days went on it was a thicker and thicker line and then the doctor confirmed it, by then it wasn't this great big excitible moment as I thought it would be because I then felt as if I already knew from the first test - not sure I am making any sense but I know what I mean!!!!! Congratulations to you, everyday you will wake up and think to yourself, ooh I wonder what changes there will be today!! It is so exciting, well done you!!
