Can your stomach bloat out if you are pregnant after only being 3 days late?

I am 3 days late with my period and to say mine comes like clockwork is an underestimation. they come every 27 or 28 days without fail, im not stressed out or anything we did have around my ovulation. i have all the early pregnancy symptoms but my 2 tests i did one over a week ago and one on the day my period was due are neg. now my stomach seems to be bloated quite a bit but no signs at all for my period, i usually have spots, chocolate cravings and really bad cramps by this stage and my periods have never been late. what do you all think? also is it poss about the bloated stomach thing?
