Microgynon 30

Hey, I was just wondering if anyone else is taking microgynon 30 and has any of these problems. My boyfriends recently noticed that I'm being extremely moody lately and that I'm over thinking loads (which I know I do already). Since taking the pill for a year now, it has been an emotional rollercoaster and I over think about my boyfriend liking other girls and that he's talking to them... but he's really not and wouldn't do that. I dunno if it's the pill but recently I have started uni and in middle of doing an essay. I've been feeling low and have cried more than I normally would during this year of taking the pill. Is this normal?
