Endometriosis ?

Hi, I’ve been having terrible pain once a month (and with my period) for the past year. The pain occurs a couple weeks after my period, it feels just like period cramps, my back & abdomen have this stabbing sensation. It’s pain that prevents me from carrying out my Day normally. Today this pain occurred and I nearly passed out from it. This pain is just as bad and sometimes worse with my period, I have severe pain when going to the bathroom on my period. I am 14 and am awkward when it comes to telling my mom, so I haven’t seen anyone about it yet. I, begin my paranoid self, googled my symptoms, and they all led to endometriosis. Does anyone know if this sounds like endometriosis or something else?
