have come on 12 days early - spoke to nhs direct and they hve advised to go to the gp in the next day or so. am really confused. i am wondering if this is the start of the menopause as i am 39. Have been having palpatations over the last few days too and general feeling of hyperactive. have been making stupid mistakes at work as well over the last few weeks and feel light headed today. does this sound like the menopause?
