So I've seen loads of threads and articles about short luteal phases potentially making TTC more difficult, but when I search effects of long luteal phases all that comes up is it could be from PCOS (which I already know I have) or that you're pregnant (hilariously that hasn't been the case for the last 180 periods so I won't hold my breath).
Does anyone know if there's any effect on TTC from a long phase? 18+ days?
