It could be a bad cycle...I notice that I have about 4 bad periods where I get easily irritable with crying spells etc. That being said it could be that you are having a bad cycle or the abilify is not working properly. This is a good topic to bring up cause as bp women it's hard to tell if there are bp symptoms or simply just our cycles. I understand why you are wondering which one it is. If I were you, I'd track yr moods for the rest of yr cycle...then when it's over track it a few days more. That way you'll know which one it is. Given all this I would still make an appt with yr pdoc.just in case it is the abilify reacting negatively. It can take a few weeks to know.if a new med is working for us or against us. A common side effect of meds that don't jive with our body is anxiety and extreme emotions as well as irritability. It's worth looking into. Good luck.
