has anyone taken Cipro, I take it for a UTI and I was wondering if anyone else has taken it because I haven't got my period yet. I've been regular all my life, so I'm just a little concerned. I was active in the last month, and I've taken two pregnancy test and they both were negative. So I'm wondering if my medication is delaying it.If anyone is familiar with Cipro please let me know what your experience was. So anything would help thanks !!
