I was on moxiflamcin antibiotics and cortozones. On the 30th August, I had sex only once, unprotected sex but Im also on birth control pills (yasmin 28's) After much worry, I only took Norlevo 4 days later... which is ast 72 days but Ive also heard sperm can stay in a womans body for up to 7 days so to be safe I took it anyway. I didnt have any unusual or withdrawal bleeding up until now... but Im told I should have had?

Im supposed to get my period today... but nothing has arrived yet and I feel a bit of cramps here and there but its my mind playing tricks on me I think. Im not sure when to start worrying about if I may be pregnant...
