Question for women about PMS, cravings, and hunger

I'm perimenopausal and hitting my first round of PMS since going primal. I have done fine up to this point; I would say I am 80/20 primal, with the 20% being dark chocolate, honey in my morning tea, 1 slice of sprouted bread in the morning, and "bad" oils in salad dressings on occasion. A little dairy if you consider that not to be primal (cream in tea, raw milk cheese once a week or so, Greek yogurt a couple times a week).
I have been moving right along, skipping some meals, doing an occasional IF, increasing my workouts, and feeling great. Have lost 12 pounds overall.
This morning I got up, found out I have gained a pound and a half in the past few days, and I was HUNGRY, and I mean hungry in a way I have not been hungry for weeks.
I ate my usual breakfast (2 eggs scrambled in coconut oil, 2 slices uncured bacon,sprouted bread w/butter, and tea with honey and cream). I work from home, so I worked through the morning.
Later I went to yoga, which usually kills my appetite for hours and I skip lunch those days, but came home starving. So I had a giant salad with the rest of a frittata from last night. Still hungry. Here is where it gets weird.
I have never made a primal dessert. I am not the kind to figure out a "primal cheat." But I did. Just spur of the moment. I put about a teaspoon of coconut oil and a teaspoon or so of almond butter in a little dish, heated them in the microwave, then added some shredded coconut. Used a square of dark chocolate to dip it out of the bowl. Almond Joy! And I feel much better.
But my question is, what the heck is going on? Anyone have Primal PMS? Will this pass? Has my IFing and meal skipping messed with me and come back to haunt me or is this something else? Should I go ahead and just listen to my hunger and eat more, eat fat (like the coconut oil and the almond butter), and see what happens?
I'm a little worried because I have felt great eating less frequently up to this point, but today it's like I have a tapeworm or something.
Thanks for any anecdotes, suggestions, or general wisdom from those who have been there, done that, and know more than I do.
