Questions about breast

My boobs are sensitive and achy when I don't have my sports bra on, but when I put it on there still a little achy but not as bad. My period should be here tomorrow, I don't really get achy boobs like this before, could this possibly be a pregnancy sysmtom? I'm going to buy a test Saturday if AF doesn't show, just wanted opnions they also tingle on and off. I also get sharp pains thru them every once in awhile.
