I'M WORRIED...Is it safe?

I've been trying to conceive for a couple months now and haven't had any luck. I decided I wasn't going to stress myself out and not think about it and act and live as normal as possible. My period is due on the 14th and now I'm worried because I had a couple alcoholic drinks this weekend, I didn't get drunk, but I did drink about four to five beers. I also like drinking herbal teas such as dietary supplements I'm not drinking them anymore, but I did drink them for about a week in this month. I just want to get opinions I'm a little worried that if I am pregnant it could affect my baby.
