is it normal for my menstrual cycle to be 3 days long?

I'm just wondering because it's been like this for the past two or three years, every time I've asked the doctor they always say it's normal but... So I just kind of needed other people's opinions . I will say my family does have a history of endometriosis oh, so I don't know if that would have something to do with it or not IP​
