... weeks before it's time for my next dose but the last three months before my last shot, I only had pms symtoms (cramping, bloating, hormonal changes but no bleeding). This three months are a little weird as well. I'm not due my next dose until July 7 but my cycle came on today. It isn't heavy or anything but it most definitely isn't just spotting either. It is about 16 days too early tho. Is this normal?
