Ladies, advice please

I know I ask a lot of questions but my doctor refuses to see me until im 12 weeks. I havent even been seen for the basics like confirmation, what to eat, not eat, .what prenatals etc. and this is my first pregnancy so please help a scared mommy to be out..
Dark chocolate? Or regular?.
I take NatureMade Multi-Prenatals but it doesnt say anything about DHA? 
And I was lookingfor the right eggs to each cause 1 DHA egg a day is reccomended but I couldnt find any that said DHA on them... How good will these be? Or go look for what brand?
