Cyclical muscle weakness

Anyone else get cyclical muscle weakness? Some weeks I feel like an infant who’s learning to hold up their head. The muscles in the back of my neck feel very weak which tends to lead to me looking down or tilting my head forward bc just holding my head up is a struggle and also makes me feel a little dizzy. I’ll also get random weakness in my forearms and drop pens or silverware. Same with my lower legs. I’m trying to track all of my weird symptoms in a planner and it seems like the last few months this all starts a few days before my period. Anyone else? Not even looking for advice, just want to see if it’s only me or if this is a common symptom? Forget working out when I feel like .
