Worried am i premenopausal or could it be somthing else.

Please help, I have always had heavy periods but my last usual one was in June. Since then, I have had two really really light periods in july. I did not have a period in august. A couple of days ago i notices a funny smell when i wiped myself after going to the loo. I had/have no discharge. I have now began a period and it is very smelly, pain full but not as heavy as a normal period would be for me. I am worried, confussed, and not sure what to do. I am aware i could have began the menopause as I am 43. But it all doesn't seem right. I always feel stupid when i visit the doctors over periods, i always feel fobbed off. I have beeb anemic in the past. due to heavy periods so i have been told. please help i dont know what i should do.
