Nervous Pregnancy

I recently took a pregnancy test and it came out positive. My boyfriend and I are very nervous well actually he is more happy then nervous so i guess its just me. But I am scared because i have been drinking the last month and was wondering if that can cause any damage to my baby. I am new to this I dont know what to do or expect during this. appreciate if i could get some help!!!

10 weeks, first OB appt at 12 weeks...

this is my 5th pregnancy, and I am currently 10 weeks along.
My first ended in a loss at 14 weeks, with hearing the heartbeat at my first OB appt at 10 weeks. My second pregnancy was a little over a year later, ending in the birth of my daughter (now 7). About 7 months after she was born I got pregnant again, ending in a loss at 12 weeks. That was in 2003. In Jan of 2010 I found out I was pregnant again, and lost it in Feb of 2010.
