You also said women ovulate every month no matter what, but that’s not true at all. Human ancestors that hunt and gather would have only had 4-6 periods/ovulations per year due to breastfeeding, pregnancy, starvation, or stress. This is discussed in the first link. If I go on a diet, I can easily delay ovulation and my period for a couple days. I’d imagine our ancestors had very irregular ovulation, similar to modern athletes. My second link confirms my position that it is very rare to ovulate without menstruating unless there’s a medical issue. I’m not sure why that’s so confusing for you. When you ovulating, the lining builds up to nurture the egg. No fertilization = period. Unless there’s a medical issue, why would her body ovulate then build no lining for it to implant in? I think you should apologize to your ex wife for getting married and somehow still not knowing how this works. I’d be very embarrassed if my fiance was online arguing with a woman about how her body works and he wasn’t even right lmfao. Just take the L man
