do I feel like this because of the pill??

Ladies, I need help. So I've been on the pill for quite some time now. I went off it for about 2 months but decided to go back on. Ever since I went back on it (same brand) I've had awful pms. Not so much cramps and physical pains but emotional distress. I'm one week away from starting my period week and I cannot control my emotions. I'm sobbing for the most ridiculous reason. And I start feeling depressed out of no where. I've never had this before even before I went on the pill initially. Also, I notice like a few days before my period I have a day or two where everything makes me so angry. It usually happens on a Wednesday. Without fail. Each time. This has been going on for a few months now and I can't take it anymore. Do you think this is the birth control that's making me this way?? I have an appointment to see my doctor but it's a few weeks away.
