Hi I'm hoping to get some advice. I'm currently 17 days late with my period although I'm not usually very regular. Never gone this long between before. I've also had sore boobs (eased now) nausea, bloating and hot flushes. My husband had the snip a few years ago under general anaesthetic where they tied his tubes after a failed standard vasectomy so can't be pregnant as he was given all clear. Is this how peri starts? I've just turned 43
