pregnant or something else???

Since thanksgiving I have been feeling quite a bit of symptoms of SOMETHING. I just need some help. been testing for a few days, keep getting negatives. 8dpo and 6 days before AF...been feeling nauseous, pooping 2-3 times a day (tmi), peeing like EVERY hour, tired all the time, upper abdomen has been hard and feeling bloated, feet have been cold as hell, and getting mild acne. I know it's too early to test and it's kinda impossible to start feelings symptoms that soon. could I be pregnant or is something else wrong???
