I have been irregular with my periods for a year, should I see a doctor?

The same situation lasted for 6 months for me. I had attributed it to stress like you, but when I went to the doctor, it turned out to be polycystic ovary. Long delays or early arrivals can sometimes be related to hormones. Honestly, it's not about being embarrassed and postponing; I would say to get it checked out as soon as possible.

In cases of such irregularities, sometimes just a blood test can provide sufficient clues. Hormone levels are checked, thyroid and prolactin are looked into, etc. So don’t worry too much that something serious will definitely come up. It's also quite unlikely that the doctors will scold you. They actually consider these things to be normal.

You said it can be two weeks early or quite delayed, is there a specific pattern? For example, how often does it tend to come on average? Or is it completely irregular? You could plan a route based on that.

Let me update you: There isn't a certain pattern; for example, it happened twice in 20 days last month, but this month there's been nothing. Honestly, this level of fluctuation is even more concerning.

I think you're making excuses about being embarrassed. I mean, you've simply delayed it; you're saying 'what if it's something serious,' but your postponement can make it more serious. Is it really that hard to go to the doctor and find a solution? Are you going to risk your health just out of fear of being scolded?

These things are also somewhat related to a person's sense of shame. But to be honest, I don't think it's right for a woman to neglect her body this much. That's the job of gynecologists, and you shouldn't be afraid of neighborhood pressure. Your health should be the priority; otherwise, you'll panic even more when you think about having kids after you get married.
