I’m not necessarily the right person to be answering this considering I haven’t had a period in years, but as someone who does have a chronic menstrual condition, I’d 1000% recommend getting it checked out. Periods are a finicky thing, if you feel uncomfortable or as if you may have an issue, then it’s worth making an appointment (especially if you mentioned there’s been a change in your discharge.)
Speaking from personal experience here, I’d try to avoid taking what the internet says at face value. There’s so much misinformation and unreliable sources online, that the information can get muddied and just cause more stress/confusion in the long haul. Some sources will say yes, others say no, and sometimes they don’t give a clear answer. Every case is unique, so sometimes it’s just better to wait and hear from a professional
