Can your S/O sense if your pregnant

So my SO swears I’m pregnant, we both sleep ALOT more than usual, I’m eating way more than I usually do sometimes I feel that “yuck” feeling but not enough to make me puke,, he said to me “I think you’re pregnant I just know , I feel like it was the last time” my period is suppose to start next week but my periods are irregular any similar stories that ended with a BFP
