HRT/Perimenopause

Hi, I don't post often, but I really need some advice and feel like I'm being dismissed at the doctors. I had some blood tests 2 years ago which confirmed I was perimenopausal. Since then I have had various symptoms, the main one being that my sex drive is non existent now. This is causing a major problem with my husband, understanding really as I am only 44. I have other symptoms such as hot flushes, irregular periods and mood swings. My question is would HRT help with all of this? Also does HRT cause weight gain and would it make my period continue or stop? So many questions but don't feel satisfied at with the doctors. I was told to go away and Google it so I thought I'd ask people with firs hand experience. Thank you.
