I need help

Rochelle

For the past several months my period hasn’t been the same the first 2 day I bleed heavy and then the next 3-4 days I have just brown! Is this normal or is this something else? I been having hot flashes not even being on my period randomly. I started my period at the age 15 I’m only 30 now! Can someone tell me they’ve gone through this or tell me what it is please?
