Girl go to the hospital to be safe. Could be nothing but better safe than sorry!

Your period shouldn't be significantly heavier just because it hasn't happened in a while. If its concerning you and/or you are bleeding through a maxi pad in an hour or less than you should for sure go to the hospital

Your period can definitely be heavy if you missed months bc your uterine lining has thickened from not bleeding regularly. This increases your risk for uterin cancer. Go to a good obgyn. She can give you meds to force you to bleed each month or I highly recommend an IUD. You may benefit from an ultrasound to see how much thickening u have. They can do a D and C to clean it out. There are so many things to try.

This happens to me too. I won’t have my period for a few months, and then I’ll get my period and it’ll either be heavy or last for an abnormally long time (ex: 3 weeks). I went to the doctor and they gave me medications to stop the bleeding.
