Is this a sign or is my body falling apart?

Well 4 days until my period and I have heart burn, a sore lower back and had a uti it's gone now but I still need to pee every 5 seconds (sorry for tmi) but I'm not sure if these are pregnancy signs or if there is something else more to blame and has anyone had these symptoms before they found out they were pregnant?

Thank you in advance 💖
