Should I talk to my doctor?

So the last two times I’ve gotten my period they have been more painful than usual during the first two days, they’ve started earlier than expected, and the flow has been heavier throughout. I’ve switched to the new Always pads that are longer that the overnight ones because the overnights couldn’t keep up with my flow! (During my last period I was changing my pads hourly and they were still soaked!!) I have been really stressed with school the past few months and I don’t know if that has anything to do with the changes..🤷🏻‍♀️ My sister keeps telling me I should talk to my doctor about these changes but I don’t know if I should. What do you think? Should I talk to my doctor about it? Should I be seriously concerned?
