I have 11 levels of bloodrager and 4 levels of dragon disciple.
Should I continue 2 more levels with dragon disciple before swithing back to bloodager?
This option will get me blindsense and +2 boost to constitution,
but I will loose 1 point of BAB, 1 point of damage reduction and also 1 spell slot and 3 spells known.

Yeah, dragon disciple is a caster-heavy class. Unlike sorcerers, bloodragers get total crap for spellcasting, so DD isn't a very good deal for you in that regard. You've already grabbed most of the good DD features (and you'd probably have to wait a lot longer to get the wings), so sticking with bloodrager henceforth sounds like a better plan.
