Antibiotics and cycle?

I remember when I used bcp's that Dr's would always say that when you were taking antibiotics to use condoms or other barrier methods because antibiotics would make the pill uneffective during the time you had to take them.   Well I'm trying to ttc and I'm currently taking antibiotics, how would that affect my O?  I'm in my O days and I'm hoping that antibiotics would not hurt ttc?  I don't know, does anyone know how antibiotics affect your cycle?

Some antibiotics can be harmful to the developing baby. I will post you a site that details them...

Having antibiotics during any stage of pregnancy can be harmful (no matter how early) so please check that you aren't having bad ones. If you are, I suggest that you delay TTC for one month.

Also, antibiotics can take 2-4 days to leave your body after you stop taking them.

I'm not pregnant. I just want to know if it'll hurt my chances of conceiving.  I'm only on them for a week. Someone told me that they make you more fertile?  I just want to know if it'll delay my O or make me skip it entirely?
