Finally a period after 2-3 years

A

Hello.. I haven’t had a period in like 2-3 years my doctor put me on BC and metformin.. she told me that my first period was gonna be a hell of a period.. well I started spotting for like 2 weeks before I started my actual period.. well not I’m changing my tampon every 1-2 hours because that’s how much blood is coming out.. I don’t feel weak of anything but I do noticed that the blood look bright red fresh.. but it smells horrible.. I have had my period for like 2 weeks so basically 4 weeks of bleeding m.. should I be worried?? Because she did saw I was gonna have a hell of a first period
