Crazy mood swings?!

I've recently started the mini pill and I've noticed I've felt nauseous often and I've been having big mood swings. I've been cryin for the past 3 hours and shaking and getting so upset just because my boyfriend wasn't replying ( I knew why, he was filming a video ) but I was getting so upset about it and j don't think I'd usually get s upset. Is this a side effect from the pill?
