The mainstream medical profession denied for some time that the Covid vaxxes had any impact upon women’s menstruation, despite women reporting many odd things occurring with their periods. This, though, is more a matter of lack of research, or a refusal to investigate reports such as included haemorrhagic bleeding lasting more than a month; heavy intermittent bleeding for four months; passing golf-ball size clots of blood and extreme cramping. If this was occurring for anything other than the sacred woke Covid vaxxes, there would be an outcry, but the matter is conveniently swept under the carpet, as with all other adverse effects from the vaxxes. Nothing to see here ladies. Disgraceful!
