Please help

OK in had sex in DEC with my partner realised the bar implant is out of date by 6 months , the condom broke , got the map the day after , in Jan I got two periods , what are the chances the map didn't work getting a white creamy discharge , never got it before , and wondering am I pregnant or is it the effects from the map? Or is it normal .

I took a test and lots negative but did I test too early ? Please help a nervous wreck .

Thank you
