Period is not coming :/

Hello...

So i had my last period at the end of december. I was in holidays and i couldn't find my pill. So when i got home i didn't take the pill for 5 days. And then i found my pill. But i didn't took it. I wanted to wait till my next period.( i asked my doc too and he said to wait till my next period.) so my period should have come on sunday. And yet still nothing :/

Had any one of you experienced this?

Should i take the pill even if i don't have my period?

Thank you for answers
