Ever since I got my booster shot im feeling I have already endometriosis, I was 2 weeks delayed after I got my booster shot and that was the first time in my whole cycle. Before my period starts I was experiencing all the symptoms related to endometriosis like leg pain,nausea and my lower back really hurts then the day I got my period it was the worst pain I experienced so far to the point I dont want to eat. My period is due this aug 13 (hopefully) and right now my pms is really worst than usual, pain all over my legs and lower abdomen. Next Month I'll be visiting a doctor if this will happen again, I THINK BOOSTER SHOT MESSED UP MY CYCLE
