Worried about having drinks

B

I’m 3 days late and took a pregnancy test that came up positive. I’m planning on taking another in the morning and then scheduling an appointment with my obgyn if that is positive as well. This month has had a lot of celebrating for me and my husband (weddings, birthdays, graduation) so we definitely had our fair share of alcoholic beverages and I probably drank more than I should have. According to this app I’m probably around 3 weeks, if I am pregnant. My question is, should I be worried that all that drinking is going to effect the baby or is it too early to do any damage. I obviously am going to stop now but it’s still worrying me.
