pms symptoms

soooo i'm having pms symptoms (tender breasts, mild mild cramping, bloating) and my period is suppose to come in exactly 7 days. my ovulation days that were predicted on this app were pretty much spot on and i ovulated with the normal 1 inch egg whitey cervical mucus about the 14th-15th ish?? i'm just wondering if it's normal to have be having these symptoms this early?
