I was diagnosed for UTI on day 13 after LMP... took cipro for 5 day... and discovered I was pregnant after 2 weeks (although I don't have regular period)... does this infection affect ovulation and/or kill off sperm in the vagina cos I heard latelty that taking cipro might cause birth defect or preterm labor... I had sex with my partner on day 12 & 16... is it possible that I got pregnant before taking cipro.. my 9 month pregnancy start on 25 August... I'm really worried..
