Possible preg?

I had sex a week ago with my DH and we use pull out but no other bc method. We are thinking about TTC but I'm now I'm feel my boobs heavy and a little sore. Should I stop drinking all alcohol? I feel like It could be just in my head but I don't want to be too dramatic cutting out all alcohol  if it's nothing (I do a lot of client dinners for my job with my boss so it's hard to avoid wine w/o people questioning it). I also was drinking all last week and nervous.
