Just wondered if anyone had any experience of pmb that reoccurred after having further investigations a few months ago I had a scan showed thickened lining/polyp had my hysteroscopy womb lining very thin no polyp or anything untoward biopsy came back clear this was end of September.bleeding stopped months ago.the past few mths hot flushes stopped then has breast soreness and bloating then a bleed started again like a light period dr now wants to resend me for a scan etc again.could it be a natural period could polyps or worse appear in a short space of time??
