Our first ob gyn appt 2nite

So I have lots of questions for the doctor, I am nervous that everything is ok with the baby and I know there are certain tests that can be done I am not sure as of how far along you have to be, I am  35 and I just hope for the best .  My mind wanders at all the things that can go wrong and I guess its normal to have concerns but I keep trying my best to push the negative  thoughts out of my head and replace it with positive thoughts of a healthy happy little baby!  I can't wait for tonights 7pm appointment and maybe that will give me peace of mind.
