There is a few reasons not to worry. One being that Augmentin is prescribed to pregnant women, and it is also prescribed to baby's, i recentally had to take it for a ear infection. When your pregnant your immune system isn't as good. That and women usually don't find out there pregnant until 4-6 weeks in, sometimes longer, and generally that early on doing something like taking anti-biotic isn't gonna have any effect. I was freaking out because i had took nightquil and Excedrin p.m, both which are big no no's while pregnant before i found out because i had the flu, and my doctor assured me not to worry, and everything was fine. But just like others have posted, it is best to avoid taking anything unless it is very very necessary, and your doctor give you an o.k. When you do to to see a doctor they will give you a list of medication that you can take.
