Period trouble

Does anyone else have trouble with their periods? Since last June I had been having them like 6-12 weeks apart. A few months I didn’t have one. And now in January I have had 2. This one that just started was 10 days early and I am bleeding heavily, I have never bled this heavily. When I went to the doctor about the irregular periods they told me it was just my weight bc I’m about 20 pounds over weight 🤷🏼‍♀️ idk what else to do
