Late/irregular period

I have an irregular period. Sometimes it takes months and even a whole year before it comes. When i was younger I wasn't bothered by its irregular schedule because I knew that I wasn't pregnant because I was a virgini. But now that I'm older and more sexually active it's starting to bother me because every time it's late I have a pregnancy Scare.

But before when this happened I would freak out about the possibility of being pregnant but then my period would come like a week or two later.

But not I'm like really losing my shit because it's been two whole months since I last had it.and I did have unprotected sex in between those to months. But idk I don't feel pregnant.. like I'm not having the symptoms, i dont even feel a baby in me. but then aging not every woman have pregnancy symptoms or even know their pregnant. .

Idk what to do. Can someone please help me..
