I am 19 years old .i just had unprotected sex but it was been pulled out. Within 7 hours I took ipill and after 12 days I got heavy bleeding for almost 7 days .then I tested negative .but it's almost 1 month I didn't get my periods but in between on the 25th day I got a little spotting .then I tested negative for second time .i also have pcos .so am I pregnant or it's just delay of periods.
