A little down

I had a UTI on thrusday and my doctor prescribed ciprofloxacin. My calendar says I'll be ovulating tomorrow and I am worried I won't get pregnant since I'm on this medication ? We have been TTC since for 3 months now and I feel like we are going to have to wait longer. It sucks that it takes so long to get pregnant now when you are actually trying grrr then there are little 16 year olds running around with babies they don't even want... Sorry for the rant. I'm done.
