Moodiness/short temper ever since I've gotten off birth control?

I stopped taking my birth control pills in June, when my fiancé and I decided to start trying for a baby.

Ever since I've gotten off of them I've had such a short temper and I'm moody and I can get aggravated over the smallest things.

I realize it, and I try to stop but I can't and I don't know what to do.

My fiancé doesn't deserve having to deal with me acting like this daily, and he says I'm so different since I've gotten off the pill.

Has this ever happened to anyone else?

Do you know why it's happening?

What can I do to stop this?

I'm desperate for some answers. Its not just PMS. It's not just right before my period, its every day.

Please give me any and all advice/suggestions. Thanks!
