Pregnant.??

So for about a week now I have had an increase in my appetite, frequent urination, & migraines. Well I tested 4 days before AF just being curious & a bfn well I was supposed to get AF yesterday & it still hasn't come so I took another a test on Saturday the day before AF was to come & Bfn again.. I haven't had any cramps just my boobs have been incredibly sore & kinda feel more firm than before.. Should I wait a couple days to test again or??
