Starting in March of this year, my period started to get very irregular. My cycle will last anywhere from 21-45 days. Some months it is closer to 3 and a half weeks, and other times it’s closer to 6-7 weeks. I’m not sure when I should start to be concerned. Since March there have been 4 times my period was longer than 35 days and 3-4 times it’s been about 21-24 days, and there’s no pattern to it. I don’t know when or if I should be concerned and if I should talk to a doctor? I’m 16 years old so I don’t think it’s the start of menopause but who knows 😂
