What is wrong!!

Oh my God.... my boobs feel like they're going to explode! Like they are really tender and sore and they just don't feel right at all. My boobs always get a little sensitive before my period but this is...I can't even compare this to anything. I wanna cry! They feel kinda solid but I haven't noticed them being any bigger. I'm also getting super irritated at EVERYTHING. I've been on the pill for four years and I thought it was supposed to help with PMS symptoms. It's never been like this. Is my PMS randomly much worse than ever or is there something wrong?
