I'm on Ciprofloxacn for an infection till Monday but was wondering how fast you can get pregnant while being on Sprintect & the antibiotic? I have taken it since August after coming off the depo provera shot have always used a condom expect for once is there a chance of becoming pregnant still if take the pill at same time every day? I havent had a period since being on the pill but i have been taking the white pills? Thanks?
