Q: Are antibiotics safe to take during pregnancy?
A: Most antibiotics are Class A and B (sometimes C) medications (see how medications are classified here) and are thus mostly safe during pregnancy. To find out more, look up the category of the antibiotic you are supposed to take.
Generally, antibiotics are needed to treat an infection, and the benefits greatly outweigh the possible risks. If you do not take the antibiotic when you need it, an untreated infection is often far higher compared to any theoretical risks from taking the medication.
