When to be concerned about heavy period?

My period has become very heavy the past couple of months and I’m starting to wonder if I should be worried. I don’t have another female to talk to about this, hence why I have to post here:

-I have to wear post partum pads every month (the really heavy Pose ones meant for after birth)

-I change my pad about every hour and a half to two hours

-this may be TMI, but when I stand up after changing my pad, I have to use toilet paper to make sure I don’t bleed out everywhere

- my blood clots are huge

-I get super dizzy and have passed out during my period before

-I have needed to wear adult diapers because of heavy bleeding

-I need to double up on my heavy pose pads a lot of the time since I’m bleeding so heavy.

I tried asking my mom about this, but she told me this was normal and not to worry. I feel like this shouldn’t be normal. Let me know what you ladies think.
