Different symptoms per period

Luna👑 • I am no ordinary woman, my dreams come true
The regular symptoms I normally get before is the odd stomach cramp the week before, and feel a little emotional. My period is due next week (I always start on the Wednesday due to the pill) and my symptoms have been all over the place! My boobs feel very tender and seemed to have gotten firmer, and awful back ache! Ive still have to odd stomach cramp, but felt more irratated than emotional! I have sex around 5 times since my last period and used a condom so I'm pretty sure I can rule out pregnancy. Does anyone else ever go through this?
