Pregnancy symptoms?

Hey ladies, I’m 7 dpo, 5 days away from af. I’ve been having sharp pains in my boobs which usually doesn’t happen for me, and last night I just wasn’t feeling well I was really cold but my face was really hot and just simply wasn’t feeling well, I’m peeing every 15-20 minutes and usually I only pee a few times a day. Could these be pregnancy symptoms this early or do you think it’s probably pms? Any ideas? Thanks!
