Pregnancy and drinking

So, in August I was pregnant and at 8 weeks we lost it. I was deviated and started to drink a bit more.... When I did a pregnancy test this month when I noticed my period was late it came back negative, and because my cycle has been so messed up, I didn't think anything of it, got upset, and have been drinking the last few nights. Couple glasses of red wine. I even had a few last night...

I just did TWO tests and they both came back positive, just 3 days after my negative test.

If my math is right, I'm about 5 weeks pregnant.... Do you think I've done damage? After the loss of our last one, I feel horrible, so guilty...and now to think I might have harmed this one.....

Help please !
