UTI antibiotics messing with me?

[psycho-lola.livejournal.com]

I've become very bloated in the last month and the main reason I would think of is because of the antibiotics I took to treat 2 UTI infections this month. I've been frequently having sex, which is probably the cause of those UTIs, although I don't think (and hope) that a pregnancy is possible since we've been using condoms and (often, not all the time) spermicide. Would that be possible? I took ciprofloxacin the two times.
