Early symptoms before period

Hi guys - just wanting some advice really I’m not sure if I’m just looking too much into it. So I am 4 days before my period and I’ve had symptoms I don’t usually have for about a week now. Extremely Gassy and stomach making gargle noises constantly- fluctuation in appetite one minute I’m so full the next I’m starving. Really bloated. heart burn that I have never had before constantly but especially on a night. Little bit of constipation. Light headache, Fatigue and Nausea to the point I’ve been close to vommiting. A change in urine smell and slightly darkened areoles-Has anyone else experienced these symptoms with a BFP at the end of it
