For several years, I had nosebleeds from just one nostril, from a 'weak' blood vessel. Not often heavy, but a nuisance and often had blood stains on the bedclothes. Eventually, I had it cauterised, to no avail, until I started HRT. The nosebleeds have stopped, except during the progesterone cycle. I wouldn't have thought nosebleeds were hormone related, but it seems a coincidence. Anyone else experienced anything similar?
