late...again!

So I'm late again, and it's starting to get to me. I've been late before normally only a week, but during that time I'd have symptoms of coming on. This time nothing and I'm nearly on my second week without a period.
I've been to the doctors and I do have PCOS, but the last 2 months I've been early or on time.
I don't wanna get my hopes up either because they always get broken.
Should I go back to the doctors or just wait it out again.
I haven't taken a test yet because I'm waiting to see if I don't come on at all.
I just need advice because I can't be doing it anymore.
