Paranoid...

I'm 7 weeks and 4 days pregnant with my second baby. I didn't find out I was pregnant until 6 weeks and before I found out I was drinking heavily. My dr appointment is on May 9th. I'm so paranoid something is wrong with the baby or even losing the baby because of me drinking. What's also worrying me is I haven't had any pregnancy symptoms besides being tired and sore boobs.
