Late!

So my boyfriend and I usually use the "pull out" method whenever we have sex, and if we want to go again in the same day we use a condom, we NEVER go again without a condom EVER. My period is three days late, it's never been three days late before, thought sometimes it is one day late. I feel very bloated and earlier this week I felt menstrual cramps but there was no blood whatsoever, and by breasts were very sore a few days ago but I think that's because I got a new bra that's too tight, should I get a pregnancy test?
