Early dark line on hpt

Candice • Awaiting our rainbow baby 4-18-15!
I got my BFP yesterday at 11dpo.  It was a strong line & stronger today.  AF is due in 2 days. The last two months
​I have had chemical pregnancies and the lines have been very faint.  Squinters in fact.
​Do you ladies think the strong lines early this time mean less chance of chemical preg?  Anyone have any experiences to share? I am feeling very positive. This baby will be due approx. 4-20-15!  Here are my lines. Top at 11dpo & bottom at 12dpo.
