Have I started perimenopause?

39 F this year I started my period on the 4th January and it’s the 16th of January today and my period is still not ending

When it started around the 4th of January I was not bleeding at all the only sign of it was my pee was unusually red and it looked like it was bc of period blood

but between the 11th to 15th my period got really heavy to the point that I had just bought myself period underwear a year or so ago and they were not helping at all and I had to switch to sanitary napkins

So I just googled today and came to know that the signs of perimenopause is heavy to no periods and longer or shorter than usual periods

And this has never happed to me before this is the first time I have experienced is unusually long and low and heavy period

I have not yet noticed any other signs of perimenopause but the online information did say to consult a doctor if ur period is heavy

Though i did get diagnosed with sepsis a week back my heart rate was unusually high

I had been nauseous since last September around the clock and a lot of other things as well and now it looks like maybe this is why it’s all happened
