Most antibiotics cause no interaction with birth control. Some do, but not many. It has become a bit of a presumption that all antibiotics cause birth control to be less reliable but this is not the case. Since a few antibiotics did, people started believing all did. There is little to no interaction between birth control and azithromycen.
If you were on active pills last week, then you were protected from pregnancy. If you only took one dose of antibiotics this week, it won't affect last week. Sperm from last week won't affect this week and this assuming there would be a reaction from the antibiotic in the first place which is not likely.
