So for the past couple days I've been feeling like im litterally on my period except my boobs dont hurt. And no nothing coming out. And my period is 2 and a half weeks away. This has never happened to me before. . Ive never felt like im on my period when my not. It feels exactly like that. My lower back is killin me and I feel full and crampy and but I usually dont cramp aaand since the other days ive been having random sharp crampy pains. Its weird and im so confused and lost rn. What could be happening? !
