[|AI|]  Hi Sally, Thanks for writing in. You have mentioned that you were suffering from bacterial infection of kidney and took antibiotics treatment. Antibiotics are known to decrease the efficacy of oral contraceptive hormone pills in some women. Coming to your delay in periods, you have said that your cycle is 28 days and regular. Your periods have been delayed this time. The home pregnancy test is most accurate (more than 95%) around 28 days after unprotected sex and following a positive pregnancy. You could repeat your home pregnancy test once after calculating 14 days following your last unprotected sex. Hope this helps.
