Do antibiotics delay fertility?

[cupcakemomof2]

I was recently (today) put on antibiotics for three days for a mild UTI, I am on the "certain" Cycle Days where it's crucial to BD every other day, I was wondering if antibiotics come in the way of messing up my fertility for this month? I was told they are "safe" to take even if I ended up getting pregnant this month, I am on CD12.

Thanks ya'll!
