Symptoms during TTW…

Is it normal to develop symptoms during the TTW? I’m not scheduled to get AF for probably 9-10 days (only about 5dpo) but my boobs are SO sore (I’ve also been having food aversions, my lower back has really been bothering me and just feel off). I’m trying not to read into it because a.) I don’t want to get my hopes up and b.) I think it would be too early? My boobs usually do get sore but not until a few days before AF. When would one start experiencing symptoms?
