Hi doctor,

I had sex with my fionce and took an ipill immediately within 2hrs as he wasn't sure if he ejected into me or not so to be on a safer side. The same happened a year back and after taking the pill I got my periods after 2-3days but this time it's been two days haven't got my periods. Is it something to worry about? Or I should be giving it more time as stress can also b a cause for delayed periods.  Is getting periods after sex a sign to say that ur safe from pregnancy?
