Period flow During Menopause

Hello I’m 49 years old experiencing pre-menopause. I got my period (after 2 months of not having it) for 19 days, started with a light flow and then towards the end it became a very heavy flow. This month of June I started the same way as the last, I’m 12 days into my current period. Is anybody going thru something similar? Any advice, is this normal?
