No PMS-No period??

It’s almost been the third week and i’m not experiencing Any period symptoms At all... my period is usually irregular. It usually comes After 3 weeks and some days...

I also took plan b 4 months ago and my period came one week late, and i also took it 8 months ago when i lost my virginity...(that’s my luck😕).

One month ago when i had Sex the last time, my period came. It wasn’t late. Real period, 7 days, heavy, with Cramps and i had all the PMS.

This month i had No sex but i don’t feel Any period symptoms.. i don’t know what to say.. usually i get PMS 5/6 days before period. I just want my period to come..sex. I’m panicking for every Little thing.

Am i panicking for nothing? I’m usually a very paranoid person due to my experiences 😆
